Department of Statistics Fall 2020 Newsletter

From the Department Head

Murali HaranI’m writing this missive during Thanksgiving week so it seems appropriate to begin with a huge round of thanks to our wonderful staff, students, and faculty: You have kept this department running smoothly during what has been a difficult and strange period for all of us. Thank you! In spite of the demands placed on so many members of the department, we have somehow navigated the COVID-19 world quite well over the past nine months. The coming months are likely to be even more challenging for us and the world at large, but perhaps hope in the form of newly developed vaccines will help carry us through the cold winter months. With any luck, the fall 2021 newsletter will be our first post COVID pandemic newsletter. 

During this past year we have been reminded repeatedly how statistics has a major role to play in understanding and solving many of the central challenges of our times, including three of the challenges that are front and center in 2020 — infectious diseases, policing, and the impact of climate change. The importance of specialized knowledge also emphasizes the importance of interdisciplinary collaborations between statisticians and domain scientists. In fact, we have faculty and graduate students at Penn State Statistics working on these very subjects in close collaboration with scientists from across the university. In this newsletter you will find a summary of several COVID-19 related research projects involving Penn State Statistics faculty and students. Of course, our department also boasts researchers working on a wide range of other important areas, from theory for high-dimensional and complex data problems, to problems in genetics, neuroscience, and social science; we plan to showcase more of our research in future newsletters and our website. 

I am delighted to welcome several outstanding new staff and faculty to our department this year. Our new research faculty bring exciting strengths to our department, for instance in the areas of neuroscience and imaging, statistical methods for understanding the structure and function of proteins, methods for studying the genetic basis of complex traits, as well as landscape ecology and statistical computing, and statistical methods for spatial data. This year we also had to bid farewell to two of our long-time and renowned faculty members, Michael Akritas and Dennis Lin. Their retirement in July is a big loss for the department. It is a loss for me personally as they have been supportive colleagues and good friends — I will miss Dennis’ sense of humor at faculty meetings and his hospitality at his wonderful parties (with interesting Chinese liquors) at his home, and I will miss chatting with Michael regularly on the 4th floor of Thomas Building, as well as at the tennis center. Please join me in wishing them well on their new adventures. You can read more about the new members of our department as well as Michael and Dennis below. 

An important role of this newsletter is to help us all to stay in touch. We have a great community both at University Park and across the world, with an extensive alumni network. You will find alumni updates in this edition of the newsletter. Please consider submitting your own update in future newsletters — it does not have to be about a major life event, it could simply be an update on where you are and what you are up to. We would love to hear from you!

With warm wishes for the holiday season and a safe and peaceful 2021.

Statistics Educators Honor C.R. Rao Centenary

CR Rao
On September 10, 2020, C.R. Rao, Emeritus Holder of the Eberly Family Chair in Statistics, celebrated his 100th birthday. The statistics community honored his considerable contributions to the field with a virtual birthday celebration at the 2020 Joint Statistical Meetings in August, a short documentary and an article in Significance, a magazine published by the Royal Statistical Society and American Statistical Association.

“C.R. Rao’s research contributions are so foundational to statistics that terms like the Cramer-Rao Lower Bound and Rao Blackwellization are familiar to everyone who has taken an introductory course in mathematical statistics,” said Murali Haran, professor and head of the Department of Statistics. “His work shaped the directions for the field of statistics in the 20th century and continues to be relevant today. Having one of the giants in the field in the Department of Statistics at Penn State raised the profile of our department and attracted outstanding scholars and students to Penn State on a regular basis.”

Rao served as a faculty member at Penn State from 1988 to 2001 and became an Emeritus Holder of the Eberly Family Chair in Statistics in 2009. He is the founding director of Penn State’s Center for Multivariate Statistics. And every other year, the statistics department honors an outstanding statistician in his name with the C. R. Rao and Bhargavi Prize.

Alumni Highlights

John Leicht

John Leicht (MAS, ’20)

John Leicht, who received a master’s degree in applied statistics in spring 2020 and completed a graduate assistantship with the Institute for Computational and Data Sciences, is now providing supercomputing support at the National Renewable Energy Laboratory in Golden, Colorado. Read the full story on news.psu.edu.

Kayne Milhomme

Kayne Milhomme (MAS, ’20)

As an intrinsically creative person who also endeavors to practice data analysis as a profession, Kayne Milhomme has strived over the course of his career to pair these two aspirations. Until recently, this path proved frustratingly elusive, leading him first into solely technical roles with little creative outlet and then into senior management positions that lacked the technical depth he was seeking. But two important events changed that trajectory for him.

First was the realization that in order to successfully apply his creative nature to an analytics role, he needed to better understand the mechanisms behind the statistical models. Without access to this advanced knowledge, his creative input was stifled by surface-level familiarity.

The second event, and most critical, was earning his MAS from Penn State. “The breadth and depth of information covered in the program provided exactly what I needed—a strong foundation to tackle innumerable real-world statistical challenges, many of which also require new, creative approaches as the world of data analytics continues to evolve,” said Kayne. The result was immediate, changing positions from senior management to senior analytics and having doors open to new and challenging analytics opportunities across disciplines, including research and development, engineering, marketing and sales.  Kayne concluded, “and the opportunities continue to grow as the field of data analytics expands, all of which I would have missed without the benefit of the MAS from Penn State.”

Angela Ting

Angela Ting (BS, ’20)

Angela Ting graduated in May 2020 with a Bachelor of Science in Statistics and Mathematics.

During her time at Penn State, she worked with Associate Professor Qunhua Li in developing and evaluating machine learning methods for genome editing outcomes as well as recovering valuable information structure from missing data. Her honors thesis was titled, “Predicting CRISPR-Cas9 Genome Editing Outcomes with Machine Learning Methods.” She also worked with Professor Dennis Pearl in creating web applications using R to estimate, model, and visualize statistical data.

Her favorite statistics course at Penn State was STAT 416 (Stochastic Processes). She says, “The course definitely gave me a strong foundation to explore and appreciate the extent of which randomness manifests itself in the systems and phenomena we encounter in our everyday lives.”

Angela is currently a first-year PhD student in Statistics at the University of Texas at Austin. She attributes her growth to all of the professors who have offered her guidance and wisdom as well as her friends and family who have supported and encouraged her throughout her educational journey.

Anna Zhang

Anna Zhang (BS, ’20)

Department of Statistics Alumna, Yinqi (Anna) Zhang, graduated with a Bachelor of Science in Statistics with minors in Mathematics and Psychology in May 2020.

While at Penn State, Zhang worked with Associate Professor Lingzhou Xue on Clustering of Bipartite Network, developing methodology and algorithms to cluster dynamic bipartite networks based on existing literature. She also worked with Professor Dennis Pearl, Research Professor of Statistics, writing Shiny apps to teach Statistics. 

Zhang said, “During my four years at Penn State, I have had the honor to get involved in research with two different professors, which gave me a solid theoretical foundation and confidence to conduct research in Social Science and bring insights from a quantitative perspective.”

Zhang is currently a first-year Ph.D. student in Educational Psychology at Penn State. She credits much of her growth in statistics to Professor Murali Haran’s teaching and mentorship.

“I took Dr. Haran’s STAT 380 (Data Science Through Statistical Reasoning and Computation) during my sophomore year. Dr. Haran put a lot of effort into teaching and was always willing to help when students struggled to learn course materials. He encouraged us to reach out to him even after class and gave me advice when I was looking for an honors supervisor for my undergraduate thesis. He also helped me write reference letters for graduate school applications. I will always be grateful for his academic advice and will do the same for my future students.”

Penn State Statistics and COVID-19 Research

Local and national collaborations develop broad understanding of the impact of the COVID virus
Le Bao

Associate Professors Le Bao and Maggie (Xiaoyue) Niu and PhD student Ying Zhang have published a paper discussing how traveler case reports could aid in a timely detection of a disease outbreak.

“Rapid detection of a disease outbreak is crucial for government intervention and raising public awareness,” says Bao. “The traveler case reports data seems to be a good addition to the domestic surveillance data by utilizing the diagnosis resources from all countries. We advocate that countries should work in a collaborative way, by sharing the traveler patient’s information about the travel dates and more detailed travel history at sub-national level, in a timely manner. Working together, we would strengthen the global infectious disease surveillance system, which is especially important in detecting disease outbreaks in countries where public health infrastructure is rudimentary or nonexistent.”

The paper, titled What Can We Learn from the Travelers Data in Detecting Disease Outbreaks — A Case Study of the COVID-19 Epidemic, was published here.

Ephraim Hanks
Associate Professor Ephraim Hanks is developing statistical methods to use all available COVID-19 data released by state agencies to understand the effect of social distancing measures and predict the future of the epidemic. This is a collaboration between multiple PSU students and faculty from the Departments of Statistics, Biology, and Biomedical Engineering, brought together in PSU’s Center for Infectious Disease Dynamics (CIDD).  Statistics PhD students Nathan Wikle and Emily Strong have also played critical roles in this project. The group is collaborating with epidemiologists from Harvard and officials in the State Departments of Health of Pennsylvania, Massachusetts, and Rhode Island. The research will offer a quantitative understanding of the effect that policies like shutdowns and cautious re-openings have on transmission rates, as well as estimates of the number of individuals who have been infected with COVID-19 unknowingly.
Mosuk Chow
Professor Mosuk Chow participated in the sample size planning part of a study that investigates the health, economic, educational and social effects of the COVID-19 pandemic in Centre County, PA, a project led by Matthew Ferrari, Huck Institutes of the Life Sciences Career Development Professor and Associate Professor of Statistics. One specific aim of the study was to follow the changes over time before and after students’ return to campus. Chow believes that this study will generate a lot of high quality data and will pave the way interesting research topics and future collaborations.
Neil Hatfield
Assistant Professor Neil Hatfield is working as a mathematics/statistics education advisor for a project led by Dr. Nathaniel Brown (Mathematics Department) and a team at University of Connecticut. The research goal is to use a social-ecological model to characterize the impacts of the COVID-19 pandemic on students of different racial/ethnic, gender, and socioeconomic status.
Helen Greatrex
Assistant Professor Helen Greatrex is studying the impact that the weather might have on COVID infections. As most of the research has focused on China and the USA, she is interested to see what the impact of other weather variables such as relative humidity, rainfall or sunshine might be. This study is part of the National Institute of Health funded P3H grant, which is led by Dr. Steven Schiff (Department of Neurosurgery), and involves a large group of Penn State scientists over many different departments. We are still learning a lot about COVID-19 and there are a lot of spatial and statistical challenges inherent in data analysis. Preliminary results suggest that the weather might be playing a small role in COVID transmission, but not enough to offset the need for social distancing.
Francesca Chiaromonte

Professor Francesca Chiaromonte (Dorothy Foehr Huck and J. Lloyd Huck Chair in Statistics for the Life Sciences), Tobia Boschi (PhD student, Statistics), and Marzia Cremona (affiliated faculty, Université Laval, Canada), with two collaborators from the Sant’Anna School of Advanced Studies in Italy — postdoc Jacopo Di Iorio and MS student Lorenzo Testa — used functional data analysis techniques to characterize the COVID-19 epidemics in Italy between February and May 2020. Using established methods and novel tools developed, the group was able to the two starkly different epidemic patterns in northern and southern Italy, and to relate mortality to mobility, positivity, and a number of socio-economic, demographic, and environmental covariates (e.g. primary care, contacts in hospitals, schools and workplaces, etc.)

The study, titled The shapes of an epidemic: using Functional Data Analysis to characterize COVID-19 in Italy can be found here.
