Interests

Systemic Lupus Erythematosus, Type I Interferons, COVID-19, Hydroxychloroquine

Research Summary

My overall research goal is to study associations between molecular signatures and clinical phenotypes that can help predict response to therapy and risk of organ damage in patients with systemic lupus erythematosus (SLE). As a post-doctoral fellow in the lab of Dr. Timothy Niewold, my research is primarily focused on the interplay between type I interferon and SLE. One particular area of interest is the association between a PRKG1 gene variant and high type I interferon activity in patients with SLE. 

As a result of the COVID-19 pandemic and its major impact in New York City, my research focus has expanded. Under the mentorship of Dr. Peter Izmirly and the NYU WARCOV initiative, led by Dr. Jose Scher, we are investigating the characteristics of patients with SLE who have developed COVID-19 and their risk factors for poor outcomes.

In addition, I have worked with Dr. Izmirly and Dr. Jill Buyon on assessing the outcomes of older patients with SLE after discontinuation of hydroxychloroquine.
