My current research interests are how NFκB dynamics informs B cell fate decision. Our lab has previously determined 6 informative NFκB dynamical features, but what remains unknown is whether cells actually use these information to make decisions – apoptosis, proliferation, division and/or differentiation. I focus on RelA and cRel, two distinct subunit of NFκB, to study signaling dynamics and their correlation with fate decision.
My research focuses on bioinformatics and data analysis. My main project involves methylation data from patients infected with cytomegalovirus post kidney transplant. I am also implementing deep learning techniques to study liver pathology images. Outside of the lab, I enjoy hiking and learning about other disciplines such as history, philosophy, and economics.
My work focuses around bioinformatics and data analysis for the lab. My current research develops single cell RNA sequencing methods for reconstructing heterogeneous time course trajectories from snapshot time series data. I have previously worked on analyzing ChIP-seq and RNA-seq data, along with performing DNA motif-oriented analysis to investigate DNA-binding mechanisms of RelA. In the UCLA BIG Summer program, I used genomic landscapes in small cell lung cancer cell lines to predict drug sensitivities. Outside the lab, some of my interests include playing the piano and guitar, engaging in community service projects for science education and mentorship, playing and watching sports, trying new cuisines, and analyzing sports data.
I joined the Hoffmann lab in June 2020. I work primarily with Dr. Quen Cheng. My research focuses on analyzing RNA-seq and ChIP-seq datasets to understand the variable outcomes of immune cells upon infection. Outside of the lab, I enjoy swimming, hiking and playing the piano.”.
As a developing physician scientist and Hematopathologist-in-training, I am interested in understanding how inflammatory signaling in the bone marrow microenvironment may influence hematopoiesis and human bone marrow disorders.

I’m a hybrid between an engineer and a biologist, with research interests centered on infection and immunity across scales. I want to study human immunity from the perspectives of systems biology and robotics. In my current work, by combining experimental tools and techniques with computational modeling, I aim to dissect how the dynamics of B-lymphocytes across scales – gene regulatory networks, cell-cell interactions, and population-level competitive selection – shape the evolution of highly specific, robust, and diverse antibody responses.
Alongside this primary research interest, I love learning about the wonderfully weird biology of exotic “non-model” organisms. I’m also passionate about global development and improving health outcomes among vulnerable populations through my work. I initiated and still contribute towards a web/mobile-based citizen science effort to crowdsource mosquito ecological data for monitoring and predicting mosquito-borne disease outbreaks [Abuzz].
As hobbies, I love hiking, cooking, playing racquet sports, Indian classical and epic music, reading comics from various countries and drawing my own, and reading sci-fi, fantasy, and non-fiction books

My research focuses on primarily on data analysis and bioinformatics in the lab. My current work deals with RNA-seq and methylation data, more specifically in differential gene expression and differential methylation analysis. I am also investigating the prediction of psoriatic arthritis using genotypic data and machine learning/deep learning techniques. Outside of the lab, I enjoy playing and watching ice hockey and basketball, hiking, and reading up on startup culture and venture capital.
