I am a PhD candidate at Yale University and an expert in Computational Biomedical technologies with over a decade of experience embedding Data Science and Artificial Intelligence to the Biomedical space.

My current research focus is on human aging and on the side I advice venture capital funds on which longevity and geroscience companies to invest in while also consulting companies at the intersection of Bioinformatics and Longevity!

As a PhD student in Computational Biology and Bioinformatics at Yale University, I am passionate about solving the mysteries of aging and extending healthy lifespans. I am developing machine learning and deep learning tools to analyze multi-omic and multi-modal data, and to answer questions such as what biological systems drive aging, how can we measure them, and can we reverse them. I am also a Yale Cancer Biology Training program fellow, where I learn about the practical clinical issues of oncology and prepare to lead translational research on teams that include both basic scientists and clinicians.

In addition to my academic research, I am a Scientific Advisor and Venture Consultant at Longevitytech.fund, a venture capital firm that focuses on investing in companies that are innovating in the fields of AI, digital health, medical devices, and diagnostics. I provide expert advice on their potential investment opportunities, and also helped them raise their second fund by building strategies for future investments. Beyond this, I have 9 years of experience in applying data science and artificial intelligence to the biomedical space, as a scientist, engineer, product manager, team builder, academician, and entrepreneur. I have worked on projects ranging from cancer prediction to metabolic regulation, and have published in prestigious journals such as Nature. I have also received multiple honors and awards, such as the Gruber Science Fellowship, Impetus Aging Grant and more.

Notable Projects

SYMPHONYAge

A single blood methylation test to quantify aging heterogeneity across 11 physiological systems

SYMPHONYAge has been patented and is currently being licensed out to multiple vendors who provide at-home aging tests

Key components of Systems Age:

  • Systems Age leverages a combination of supervised and unsupervised machine learning approaches to find latent dimensions of organ specific aging. Its 5 step process which uses a mixture of classical machine learning methods and more novel neural network approaches is able to model 11 different organ aging scores from 450K methylation features and 20K samples.

  • Systems age is a first of its kind epigentic biomarker which can untangle organ level aging from just one single blood draw. This allows systems age to not only give more insight into organ aging but also makes it a more precise biomarker than it whole body aging epigenetic biomarker counterparts

  • Having 11 different organ level scores from a single blood draw allows for categorisation of individuals into ageotypes that have increased pre-disposition to specific aging related diseases and conditions.

Aging DB

Using publicly available data we built a platform to understand which anti-aging interventions were modifying aging biomarkers the most and in-turn which aging biomarkers were responding the most to interventions.

AIOmic and DMDB

AIOmic stands for AI enabled Integrative Omics pipeline and was specially built for Drug Metabolism Database (DMDB) to integrate and analyse data from 500 drugs in 50 cell lines over 5 years.

  • Very often “Integration of Omics data” refers to generation of multiple Omics data and viewing them in parallel. AIOmic on the other hand integrates all 4 of its Omic data to view on the same KEGG Network.

  • One of the biggest challenges in large multi-omic data sets is to find succinct biological insights by manually scavenging the data. AIOmic automates this by using publicly available information to find relevant insights.

  • DMDB with its 4 Omics datasets and integration gives a holistic and multi-pronged view of metabolism at different levels of the cellular processes.
