Current Research Interests

CFD modeling of OR air flow (Montefiore Medical Center/ Mt. Sinai Medical Center) – Part of the Mt. Sinai MOU exchange program.

Partnered with Dr. Calin Moucha, Associate Professor of Orthopedics and Orthopedic Surgery at Mt. Sinai, and Dr. Mitchell Weiser, Instructor of Orthopaedic Surgery at Albert Einstein College of Medicine and Montefiore Medical Center, in an effort to model air flow for post-operative infection prevention. This project utilizes operating room airflow measurements, including pressure, speed, and direction, to build a computer model of airflow patterns in the operating room. Several different conditions that may affect operating room airflow patterns are examined and modeled including single and double door opening events, the use of forced air warmers versus conductive heating blankets to maintain patient normothermia, and the effect of obstructing air exhaust vents with surgical equipment. The goal of this project is to more precisely model and understand operating room airflow patterns during common scenarios to help determine optimal operating room equipment layouts and best-practices.


Controlled Release of microparticles from spinal bioadhesives for herniated disc injuries (in collaboration with Mt. Sinai Icahn School of Medicine)

Partnered with Dr. James Iatridis, a Professor of Orthopedics and Neurology at ISMMS. The goal of this project is to encapsulate extracellular vesicles, called exosomes, which are responsible for promoting wound healing into polymer microparticles. The work involves developing protocols for the encapsulation of exosomes into PLGA microparticles and the addition of these particles into the in situ synthesis of interpenetrating network (IPN) polymer bioadhesives for spinal disc herniation. We are studying the effect that the number of microparticle per IPN scaffold has on the material properties of the scaffolds and their degradation characteristics.  


Open source, inexpensive syringe pumps for various applications (in collaboration with New York University)

Partnered with Dr. Simon Peron, a Professor of Neural Science at NYU, to develop inexpensive syringe pumps for multiple applications. Dr. Peron’s lab uses a pump system in the conditioning of animals to study neural pathways. My own work uses syringe pumps for creating electrospun polymer scaffolds. There is a need to have more access to inexpensive systems for scientific research. The goal of this project is to create an inexpensive, open source method for other research labs to create their own syringe pumps.

 

Electrospun polymer fibers for direct carbon capture applications

Partnered with Professor Amanda Simson to develop polymer systems for direct carbon capture. The work involves adapting different polymer combinations to create microscale electrospun fibers that will contain direct carbon capture resins. These embedded resins will be able to directly capture carbon from the air and then be regenerated using water. The goal is to characterize the systems chemically and then understand the kinetics of the absorption/desorption steps.
