Research Focus

Molecular science in service of patients.

My research spans three interrelated domains — each grounded in rigorous molecular science and oriented toward understanding disease at the level that changes what physicians can offer.

T-Cell Biology & Immunoengineering

Investigating how microRNAs and signaling cascades — particularly the miR-15a/16–MEK1–ERK1/2–Elk1 axis — govern T-cell activation and proliferative capacity, with implications for autoimmunity, oncology, and post-surgical immune regulation.

Biomaterial & Organoid Platforms

Designing immune-instructive biomaterials and patient-derived organoid systems that recapitulate disease microenvironments — bridging bench discoveries to testable therapeutic hypotheses.

Translational Immunology

Connecting molecular-level discoveries in immune signaling to measurable clinical outcomes — spanning oncology, infectious disease, and chronic inflammatory conditions.

Nature Biomed EngIF 28.1202262 citations

Engineered mesoporous biomaterials that capture bacterial PAMPs in vivo generate durable immune protection against sepsis — a translational platform with direct relevance to post-surgical infection prevention.

Biomaterial vaccines capturing pathogen-associated molecular patterns protect against bacterial infections and septic shock.

Identified miR-15a/16 as a molecular brake on T-cell proliferation, demonstrating that activation-induced microRNA downregulation gates the MEK–ERK axis — a finding with therapeutic implications for autoimmunity and immunotherapy.

T-cell activation decreases miRNA-15a/16 levels to promote MEK1–ERK1/2–Elk1 signaling and proliferative capacity.

Selenoprotein I functions as a metabolic regulator of T-cell fate decisions, shifting the Treg/Th17 balance — with implications for controlling post-operative inflammation and autoimmune flares.

Selenoprotein I deficiency in T cells promotes differentiation into tolerant phenotypes while decreasing Th17 pathology.

Clinical Training

Medicine as the destination for science.

My clinical training is built on a simple conviction: the best physicians are the ones who understand disease at a molecular level. Every rotation sharpens my ability to ask the right question — and to know which experiments would answer it.

I have not yet committed to a specialty. I am deliberately keeping an open mind through clinical exposure, pursuing programs with strong research infrastructure and physician-scientist tracks.

Areas of Clinical Interest

  • Internal Medicine & Complex Disease
  • Oncology & Immuno-Oncology
  • Infectious Disease & Host Immunity
  • Serious Illness Communication
  • Evidence-Based & Translational Practice
“The physician-scientist is not two jobs — it is one vocation: to understand disease deeply enough to change it.”

Curriculum Vitae

Academic & clinical
record at a glance.

A decade of continuous research — from CRO preclinical studies to Nature-published biomaterials to Harvard postdoctoral fellowship — integrated with structured medical training and a commitment to building a physician-scientist career.
