She thoroughly enjoys being part of the team and is excited for the future of the institute. When she is not at work Samry enjoys working out, cooking/hosting for friends, listening to podcasts, reading and working on her crochet projects

Ritwik Anand

PhD Student

Ritwik’s focus is in extending and applying causal theory to handle biomolecular systems. Developing models to handle the feedback loops and dynamics of such networks, and algorithms to handle the noise and uncertainty typically seen in biological data. Outside of research Ritwik enjoys traveling, hiking, climbing, cooking and raving until his joints can’t function.

Devon Kohler

PhD Student

Devon joins Northeastern University from Nantucket, MA. His research focuses on leveraging statistical and causal inference to uncover insights in proteomics. Outside of the lab, Devon can be found surfing, snowboarding, or just hanging out with his cat

Sai Srikanth Lakkimsetty

PhD Student

Ethan Rogers 

PhD Student

Ethan’s research focuses on statistical methods for analyzing mass spectrometry imaging data in experiments with complex designs. Outside of research Ethan enjoys traveling, cooking, trying new foods, and being outdoors.

Sarah Szvetecz

PhD Student

Sarah is interested in developing statistical and machine learning methods to analyze chemoproteomics data, with a focus on drug response prediction and target identification. Outside of the lab, she enjoys yoga, exploring new vegan restaurants, and making the most of New England’s seasons, from summer days at the beach to skiing in the winter.

Vartika Tewari

PhD Student

Vartika is a PhD student in Olga Vitek’s lab, where her research focuses on developing causal generative AI models for realistic mass spectrometry data generation. She is particularly interested in how these models can improve experimental design and advance statistical learning for proteomics. Outside of research, she loves cooking vegetarian food from around the world and exploring new hiking trails.

Tony Wu

PhD Student

Tony specializes in computational biology with a focus on mass spectrometry-based proteomics and causal inference. His research involves developing graph-based algorithms to analyze biomolecular networks, addressing challenges like batch effects and hypothesis generation from proteomics data. Outside of research, Tony enjoys cooking, especially experimenting with Chinese cuisine, and playing in a 32-team dynasty fantasy basketball league. He is focused on improving his Chinese reading skills through reading short stories.

Yinyue Zhu  

PhD Student

Yinyue’s research focuses on developing analysis methods for ion mobility mass spectrometry imaging data, he is also interested in improving analyze identification in mass spectrometry imaging.
In his free time, Yinyue enjoys biking, cooking Sichuanese food, and reading National Geographic.
