I am focused on the formation and characterization of supported lipid bilayers (SLB) using mammalian and bacterial cell membranes on conducting polymer surfaces. As part of my research, I isolate cell blebs from mammalian cells and outer membrane vesicles (OMVs) from bacteria and rupture them on conducting polymer-coated glass slides. Then I characterize the membranes using Fluorescence Recovery After Photobleaching (FRAP) and Quartz Microbalance with Dissipation (QCM-D). These SLB platforms can be used for a variety of studies including virus fusion, ion channel activity, and protein dynamics.

Fun Facts

When I’m not in the lab, I enjoy traveling. During my time in the US, I have visited twelve states: California, Arizona, Utah, Texas, New York, Pennsylvania, Florida, Illinois, Missouri, Maryland, Washington D.C., and Washington. I look forward to visiting all fifty states in order to learn about regional nuances because this knowledge helps me work with diverse teams. My hobbies outside of travel are cooking, hiking, and following my favorite teams: Barcelona Football, English Premier League, and Team India Cricket.
