I am a Forbes 30 Under 30 honoree and Faculty at Yale University using AI for Longevity Science, with over a decade of experience integrating Data Science and Artificial Intelligence into the biomedical field.

My current research focuses on human aging, and I also advise venture capital funds on investment opportunities in the longevity and geroscience space. Additionally, I advise and consult start-ups at the intersection of AI and longevity!

As a Faculty at Yale, 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. As part of my research I built SYMPHONYAge a patented biomarker that can measure aging in 11 different organs of your body from a single blood draw. The biomarker is available to patients and clinicians via TruDiagnostic where I also serve as a Scientific Advisory Board member.  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 Principal at Longevity Tech 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 10 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 has been licensed out to TruDiagnostic

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.

TranslAGE

Validating aging biomarkers for Prognostic, Responsive, and Reliable qualities is essential for clinical use. TranslAGE offers a framework to standardize this process, leveraging public data to streamline aging biomarker translation. As a proof of concept, we applied this framework to over 110 DNAm aging biomarkers, ranking their potential as clinical surrogate endpoints, with plans to extend this framework to other Omic biomarkers.

  • Prognostic analysis looking at data from 21K individuals from Asian, South Asian, European, African, Hispanic and Native American ancestries across 40+ aging phenotypes with the goal to find the most predictive aging biomarkers

  • We looked at 51 different longevity interventions and whether aging biomarkers respond to them.

  • We looked at technical and biological reliability linking it back to prognosis and reliable

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.

    SYMPHONYAge (System Methylation Proxy of Heterogeneous Organ Years), this collection of system-specific clocks provides a new way of looking at aging by examining how different parts of the body decline independently, and synchronously, over time. Due to lifestyle and dietary choices, researchers explain that organ systems age differently in a single body, and that disease-related risks can be calculated by examining 11 major systems and their biological effect on one another. This includes: Lung Age, Heart Age, Brain Age, Hormone Age, Metabolic Age, Musculoskeletal Age, Blood Age, Liver Age, Inflammation Age, Kidney Age, and Immune System Age.
