Frederick A. "Erick" Matsen

Professor, Fred Hutchinson Cancer Research Center;

Affiliate Professor, Genome Sciences & Statistics, University of Washington;

Investigator, Howard Hughes Medical Institute


Research statement: I'm interested in developing Bayesian phylogenetics as an optimization problem, and in understanding the process by which the adaptive immune system learns to recognize foreign antigen.

Personal interests: Historically I've loved climbing, backcountry skiing and kayaking; right now I'm raising two kids.

Hometown: Seattle, WA

Duncan Ralph

Staff scientist


Research statement: I develop computational methods for inference on B cell receptor deep sequencing data, and apply these methods to data from wet lab collaborators at the Hutch and elsewhere. Recent projects include recapitulating the development of broadly-neutralizing anti-HIV antibodies, and choosing antibodies from deep sequencing data for synthesis and testing against dengue virus.

Personal interests: In town I run and gym climb; out of town I climb and ski in the mountains.

Hometown: Arcata, CA

Will DeWitt

Genome Sciences PhD student (joint with Kelley Harris)


Research statement: I’m broadly interested in computational and mathematical biology, and focus on both quantitative immunology and evolutionary genomics.

Personal interests: I enjoy playing in the snow, cooking, gazing at sunsets, photographing birds, and playing guitar and ukulele.

Hometown: Bradford, VT

Thayer Fisher

Biostatistics PhD student


Research statement: I am interested in how we can model and simulate how B cells mutate at the mechanistic level.

Personal interests: In my spare time I enjoy watching and playing soccer, rock climbing, and playing chess.

Jared G. Galloway



Research statement: I’m fascinated by all facets of biology. Recently, I’ve focused my energy on protein-antibody interaction studies where high throughput protocols, big data, and statistics intersect.

Personal interests: My time is primarily spent cycling, listening to podcasts of a wide variety, reading, skiing, and annoying my cat.

Hometown: Bozeman, MT

Zorian Thornton

Genome Sciences PhD student


Research statement: I am interested in studying how mutations impact the biophysical properties of antibodies and quickly evolving viral proteins using interpretable deep neural networks.

Personal interests: In my free time I enjoy watching history documentaries, blogging, making YouTube videos, baking sweets, playing and watching sports and powerlifting.

Hometown: Goochland, VA

Magdalena "Maggie" Russell

Molecular and Cellular Biology PhD student


Research statement: I’m interested in identifying and understanding genetic biases during the T cell receptor generation process, and how they lead to repertoire variability across individuals and in the context of disease.

Personal interests: I enjoy hiking, cross country and downhill skiing, baking, painting, and crocheting!

Hometown: Bozeman, MT

Kevin Sung

Postdoc (joint with Julie Overbaugh)


Research statement: I’m interested in applying mathematical and statistical methods to a variety of topics in immunology.

Personal interests: Sports and food! Particularly basketball and tiramisu...

Hometown: Toronto, ON, Canada

Hassan Nasif

Statistics PhD student


Research statement: I’m interested in developing fast and statistically rigorous algorithms for Bayesian phylogenetic inference, with a focus on variational inference and optimization.

Personal interests: I love to hike, weightlift, read science fiction, play board games, and enjoy good coffee/tea/food with friends.

Hometown: Raleigh, NC

Will Dumm



Research statement: I’m interested in using math to develop new algorithms for phylogenetic inference.

Personal interests: I enjoy hiking, swimming, flying, kayaking, playing violin, and searching for abandoned and unpicked fruit trees.

Hometown: Kodiak, AK

David Rich



Personal interests: I enjoy hiking, fly fishing, horseback riding, playing guitar, and gaming.

Hometown: Seeley Lake, MT

Thien Tran

Undergraduate assistant


Personal interests: I really love skiing, hiking, and visiting new places with my friends and family! In my free time, I enjoy baking bagels, watching sunsets, and taking care of my olive tree.

Hometown: Everett, WA

Ognian Milanov



Research statement: I'm passionate about finding elegant C++ designs and implementations for complex real-world and theoretical problems.

Personal interests: Raising kids, off roading, homesteading.

Hometown: Novachene, Bulgaria

Assya Trofimov

Postdoc (joint with Armita Nourmohammad and Phil Bradley, starting Jan 2021)


Research statement: First trained in biochemistry, then computational biology, I will be attempting to model the relationship between an individual's genetic background and their TCR repertoire.

Personal interests: I really enjoy strategy, worker placement and resource management board games - I play every week. I also love videogames, but I’m now great at them. I am a baker - I particularly enjoy trying out new techniques.

Hometown: Montreal, Quebec, Canada

Chris Jennings-Shaffer

Postdoc (starting Jan 2021)


Research statement: While I was trained as a number theorist (you can find my articles on, my work has always been computational and now I focus on data science. I am interested in how mathematics applies to solving problems in biology.

Personal interests: I enjoy the occasional hike when the weather is nice, but really I like sitting at home with food and drinks. I should get a cat.
