FROM THE DESK OF THE DEPARTMENT HEAD
This newsletter is a team effort, and I’d like to start by thanking Kathy Smith in particular for all of her behind-the-scenes work not only on this project, but in maintaining our department website in general. Unlike the newsletters of the past, this new incarnation is web-based, and we’ll take advantage of this format by occasionally inserting links into the text for those who wish to delve deeper. There will of course be a bit of overlap with what’s already on our web pages, but this separate document will allow us to spotlight certain items and provide an easily browsable format for the hundreds of people worldwide with a strong connection to Penn State’s Department of Statistics.
I’m now halfway through my fourth year (!) as department head, so it would take several e-issues of the newsletter—which we plan to update every semester—to catch up on the past several years’ happenings. Rather than trying to give a comprehensive account, I’ll kick off this first issue by mentioning some of the major stories.
First and foremost, we have many new faculty members (fourteen, to be exact) and staff members (four of them) who have joined our department since I became head in the summer of 2012. You can read brief introductions to them below.
One development that has been accelerating over the past couple years is our department’s ascendance as a center for statistics education. For over a decade, our online program has been creating a reputation as one of the strongest in the nation as we have continued to build our expertise in this area. More recently, we have hired several faculty members with strong research interests in statistics education, and they are featured in a nice article that appeared in the December 2015 issue of Penn State’s Science Journal. While it’s difficult to replace giants like our former colleagues Bill Harkness and Bob Heckard who have retired, our current faculty are carrying on their tradition of educational innovation.
Other features in this issue of the newsletter include a rundown of upcoming events, a synopsis of some of the major departmental events of 2015, and various news items—by no means an exhaustive list—involving our faculty and students. There have been quite a few births to members of the department, and one of our former graduate students has chronicled her recent 16-month bicycle trip from one end of the Americas to the other. Finally, we include a short tribute to two very good friends and colleagues we lost recently, along with links to full obituaries.
Until our next issue of the newsletter in the summer semester, I wish you all the best and I hope everyone’s 2016 is off to a great start!
David Hunter, Department Head
The bi-annual Clogg Memorial lectures will be held March 21-23, 2016. This year’s speaker, chosen by a joint committee of statistics and sociology faculty members, is Mark Handcock of the University of California, Los Angeles. Dr. Handcock, who is currently the chair of UCLA’s Department of Statistics, is an affiliate of the California Center for Population Research and is well-known for his statistical work in the social sciences.
The Clogg Lectures, which honor the contributions of a former Distinguished Professor of Statistics and Sociology at Penn State, feature speakers whose work bridges the fields of statistics and sociology. The selection committee is always comprised of faculty from both departments, but by design the two departments alternate in taking the lead on selecting the honorees.
Inaugural Marker Lectures in Statistics
The first-ever Marker Lectures in Statistics will be delivered by Dr. Bin Yu from the University of California, Berkeley. We are organizing her visit jointly with the Department of Public Health Sciences (which includes Penn State’s biostatistics group) at the Hershey medical campus, and our hope is that the Marker Lectures can continue in this mode in the future and serve as a means to facilitate interaction between our two departments. Dr. Yu, who is a member of the United States National Academy of Sciences, will give one talk in the Statistics Department on Tuesday, April 26 and another the next day in Hershey. More details will be forthcoming once schedules are firmed up.
This year DataFest is scheduled for April 22-24, 2016. Check out our description of DataFest 2015 at Penn State.
The 2016 Electronic Conference on Teaching Statistics (eCOTS) will take place May 16-20, 2016. This year eCOTS 2016 will feature two keynote speakers: Andrew Gelman from Columbia University and Michael Jordan from University of California, Berkeley. eCOTS will also include virtual panel discussions, breakout sessions, workshops, posters, birds-of-a-feather discussions, and new this year, some regional face-to-face mini-conferences connecting to eCOTS.
2015 EVENTS IN REVIEW
The conference was partly organized by Dennis Pearl, who joined our faculty in 2014, and several staff members and graduate students, notably Kathy Smith, Lorey Burghard, and Bob Carey. The conference website, which includes links to presenter materials, is still maintained at CAUSEweb.org (hosted at Penn State ever since Dennis arrived here). An article describing USCOTS 2015 appeared in the online version of AmStat News in October 2015.
DataFest originated at UCLA in 2011 and is now sponsored by the American Statistical Association. We are already looking forward to Datafest 2016, scheduled for the weekend of April 22-24. Each year’s DataFest uses the same dataset, which is not announced beforehand, at all sites around the country.

What can ants teach us about the transmission and spread of human disease? Perhaps a lot, according to a team of researchers who recently received a grant of more than $1.8 million from the National Science Foundation to explore this question. The research project, led by principal investigator Dr. David Hughes (Entomology/Biology), has a strong statistical component led by Dr. Ephraim Hanks, Assistant Professor in the Department of Statistics.
A new study published in Scientific Reports suggests corals may have a greater capacity to adapt to changing ocean conditions than experts thought. This study involved a collaboration between biologists John Everett Parkinson, Anastazia T. Banaszak, Todd C. LaJeunesse, and Iliana B. Baums, and Professor Naomi S. Altman in the Department of Statistics.
The Statistical and Applied Mathematical Sciences Institute (SAMSI) in Research Triangle Park, North Carolina, fosters new collaborations among researchers at multiple institutions around the world by bringing them together for semester or year-long programs. A recent Amstat News article highlighted a SAMSI research group focused on statistical methods for studying paleoclimate for, remarkably, continuing to work together five years after the SAMSI program that brought them together officially concluded. The research group includes two Penn State faculty, Martin Tingley (Meteorology/Statistics) and Murali Haran (Statistics), along with Peter Craigmile (Ohio State), Bo Li (U of Illinois), Elizabeth Mannshardt (NC State) and Bala Rajaratnam (Stanford). The researchers began meeting as part of the 2009–2010 SAMSI program on Space-Time Analysis for Environmental Mapping, Epidemiology, and Climate Change.
Professor Francesca Chiaromonte of the Department of Statistics was part of a research group that published results on a large study of mutations in mitochondrial DNA. A multidisciplinary Penn State and UC Berkley team including researchers in genomics, bioinformatics, medical sciences, forensic sciences and statistics produced and analyzed breakthrough data on mutations that accrue as human mitochondria are passed from mothers to children. These mutations are involved in a large number of diseases. The findings that mitochondrial DNA molecules undergo a small bottleneck, and that mutations are more common in children of older mothers, are therefore critical for genetic counseling. This work was published in the Proceedings of the National Academy of Sciences.
The National Science Foundation’s Division of Mathematical Sciences has awarded more than $500,000 to Penn State to develop new statistical methods needed for predicting the future of Antarctic ice sheets, which now are melting at an alarming rate. The Penn State research group involves principal investigator Murali Haran in the Department of Statistics, Chris Forest in Meteorology, and David Pollard and Patrick Applegate from the Earth and Environmental Systems Institute.
A National Institutes of Health Big Data to Knowledge Program grant to Donna Coffman, research associate professor in Penn State’s College of Health and Human Development and principal investigator at the Methodology Center, targets the development of big data methods for biobehavioral change and maintenance.

Around the Department
The Department of Statistics offers two vibrant online programs, the Certificate in Applied Statistics, a 12 credit graduate certificate program, and the professional Master of Applied Statistics. Both programs continue to grow in enrollment. During the fall 2015 semester, we had 27 course sections, and an additional 17 lower level undergraduate classes online. This spring 2016 there are a total of 49 sections, with 40 instructors and professors teaching online. The program provides much sought after educational opportunities in applied statistics, primarily for students who are working full or part time who cannot attend a residential program. Many are also mid-career, with advanced degrees in another field. For the M.A.S. degree we admit about 12 students per year in the residential program, and nearly 90 in the online program.
The Statistical Consulting Center provides short term statistical consulting to clients who are primarily graduate students at the university. In addition, longer term projects and collaboration of research projects are encouraged. These consulting meetings provide our M.A.S., M.S., and Ph.D. students with real world experience in working with clients. Recent news from the SCC: Maggie Nui was appointed as the associate director beginning last year, and Stefanie Austin holds a joint appointment between the Penn State Library Data Learning Center and the SCC. These library services are in keeping with an expended mission of the library, and the SCC is recognized as part of a network of services which are available to researchers at Penn State.
Statistics Department recognized for positive contributions to the college climate and diversity.
The Dean’s Climate and Diversity Awards Recipients for 2015 went to the Physics and Astronomy for Women graduate student group for their outreach work, Star Sharpe, the Director of the Millennium Scholars Program for her work with the diverse group of undergraduates students providing foundations that will serve them through graduate studies, as well as Dr. Stephen Schaeffer for his advising and mentoring of graduate students in the Department Biology.
In the Department of Statistics, Laura Burghard was recognized for her initiative and contributions in promoting a positive climate and atmosphere in her work with the Consortium for the Advancement of Undergraduate Statistics Education (CAUSE), and through her many activities related to fund raising for the United Way in addition to her work in spearheading much of the recent renovation work that has taken place in the department. Graduate students Meredith Bartley and Sayali Phadke were also recognized for their efforts helping to found what is now the Statistics Graduate Student Association which is also an affiliate of the universities Graduate and Professional Student Association. This group organizes and holds regular and very popular workshops and events for students. Laura’s, Meredith’s and Sayali’s efforts continue to stimulate positive energy and a collegiality among the students, faculty and staff in the department.
In the previous year, Stefanie Austin won one of the college-wide awards for her efforts to revitalize the Stat Club, a group comprised mostly of undergraduate statistics majors but with a few graduate students as well. The Stat Club organizes various activities for students including an annual career fair that attracts representatives from various companies in our area who hire statisticians.
Dr. Bruce Lindsay
Dr. Lindsay joined our faculty in 1979 as an assistant professor and spent the next 36 years fulfilling the roles of teacher, researcher, mentor, and department head. He was recognized as a world leading researcher in multiple fields, including mixture modeling, likelihood approximations, and model selection, to name just a few areas where his research has had a major impact. He was also a beloved mentor to a large number of Ph.D. students, most of whom have gone on to very successful careers of their own. He was the holder of the Eberly Family Chair in Statistics, one of the highest honors awarded to faculty members in Penn State’s Eberly College of Science.
The August 2015 issue of the IMS bulletin published a full obituary for Bruce.
Dr. Steven Arnold
Dr. Arnold joined the department in 1976, and with his booming voice he could often be heard up and down the halls of Pond Lab, then Thomas Building discussing all manner of statistical topics. Chief among these topics, of course, was the field of linear statistical models, on which he taught a well-known graduate course to hundreds of Ph.D. students over the years using the textbook he wrote himself. He also proposed and served as the founding faculty member in charge of the new undergraduate major in Statistics, guided it through the Faculty Senate for approval, and directed the program for eight years.
The March 2015 issue of the IMS bulletin published a full obituary for Steve.
The Department proud to announce the birth of children to our faculty and staff in the past year!
Stefani Austin and her husband, Peter announced the birth of their daughter Phoebe in September 2015.
Kari Lock Morgan and her husband Eugene also announced the birth of their daughter Daisy in October of this year.
Qunhua Li and her husband Zibiao have also announced the birth of their second child, also a daughter born in November 2015.
Maggie Niu and Le Bao announced the birth of their second daughter Bella in December of 2014.
Adventures of Daisy Philtron, the roaming statistician!
In Daisy’s words: Last year my husband and I spent 16 months riding our bicycles on the Pan-American route between Anchorage, Alaska and Chilean Patagonia. We pedaled 17,445 miles over 485 days, and traveled through nine countries. We were entirely self-sufficient, carrying our own tent, cooking supplies, food, water, and entertainment. During the first 4 months of the trip I wrote my dissertation. Each night in the tent I worked diligently on a laptop we carried, until that delightful day in September, 2014 when we flew back to State College for my defense.
For the next 11 months we rode in Latin America. Words are insufficient to describe how fantastic this portion of the trip was. Mexico in particular is a gorgeous country with friendly people and excellent food. In South America we experienced sublime scenery, local hospitality, and challenging conditions. We spent over a month above 14,000’ elevation in Bolivia, surviving extremes of cold and altitude. In Ecuador we battled mudslides, in Colombia we had to get on the road at 5 am to beat the heat, and in Peru we climbed mountains daily. Once we managed to gain 9,000 vertical feet in single day. Throughout the trip we navigated large cities, tiny towns, the Spanish language, civil protests, and busy roads filled with swerving buses. It was a collection of unforgettable experiences that renewed our faith in people everywhere and increased our awe for the Andes, the desert, and for indoor plumbing. If you want to read more about the trip, visit the website thephiltrons.com and watch for announcements about presentations in the department and at the outdoor stores downtown.
