Lab members
Abraham (Bram) Teunissen, PhD
Role: Principal Investigator
Dr. Teunissen received his M.Sc. degree in Molecular Engineering from the Eindhoven University of Technology, the Netherlands. He completed his Ph.D. at the same University, in the group of Dr. E.W. Meijer. His graduate research involved developing biomimetic supramolecular systems and synthetic chemical reaction networks. From 2017 to 2019, Dr. Teunissen was a postdoctoral fellow in the Mulder lab at the Icahn School of Medicine at Mount Sinai. Here, he developed nanotherapeutics for modulating the innate immune system and employed these to treat cardiovascular disease and cancer. His lab currently focuses on developing and employing tools for modulating and monitoring trained immunity in vivo, with a emphasis on organ transplantation. Dr. Teunissen is also the founding director of the radiochemistry facility at Mount Sinai’s Biomedical Engineering and Imaging Institute.
Bidisha Dutta, PhD
Role: Postdoctoral Fellow
Hello, I’m Bidisha. I completed my Ph.D. in 2024 at the University of Maryland, College Park. During my Ph.D., I investigated the role of the mechanosensitive ion channel TRPV4 in regulating fibroinflammatory diseases such as atherosclerosis. My work in basic immunology research during my Ph.D. sparked my interest in joining a more translational research group that integrates foundational science with clinical applications. This made the Teunissen Lab an excellent fit for me, because of the extensive involvement of the lab in designing and developing nanotherapeutics for diseases like cancer and cardiovascular conditions. I will be working as a postdoctoral researcher in the lab to study how trained immunity develops and manifests in the context of organ transplantation. I am excited to deepen my knowledge and skills through collaboration as well as through leveraging the resources available in the lab.
Krystyna Demkiw, PhD
Role: Postdoctoral Fellow
Hi, I’m Krystyna! I received my Ph.D. in organic chemistry in 2023 from New York University. My graduate research was primarily focused on investigating the role of halogen atoms in directing the stereochemical outcomes of nucleophilic substitution reactions of acetals. I am delighted to continue my learning in the Teunissen lab by expanding my knowledge in radiochemisty and nanotherapeutics. As a postdoc, I am working on the radiosynthesis and radiolabeling of PET probes for the detection and treatment of various cancers. Additionally, I am synthesizing different prodrugs for the development of new nanotherapeutics. It is exciting to be a part of such an interdisciplinary group, and I look forward to learn and grow by developing novel therapeutics and exploring their applications!.
Myrthe Kapteijns
Role: Master Student
Hi, I’m Myrthe! I am a Biomedical Engineering master’s student at Eindhoven University of Technology (TU/e) in the Netherlands, and I am currently completing my master’s degree through an internship in the Teunissen lab. During my studies in Eindhoven, my research primarily focused on apolipoprotein A1 lipid nanoparticles, with emphasis on storage and stability studies and the development of a high-throughput screening approach using DNA barcoding. Through this internship, I am excited to further expand my skill set by learning new techniques such as radiochemistry and in vivo experimentation. I am motivated by research that bridges engineering, biology, and medicine to enable the clinical translation of nanotherapeutics, and I look forward to learning and growing as a part of the Teunissen lab.
Sheikh Jobayar
Role: Research Assistant
Hi everyone, I’m Sheikh! I graduated from Barnard College in May 2024 with a Bachelor’s degree in Chemistry. At Barnard, I worked in the Rojas Lab for two years, focusing on two projects. The first focused on stereoselective, fully intramolecular synthesis of 1,2,3-all-cis-2-amino sugars. The second focused on the synthesis of SMIFH2 (small-molecule inhibitor of the FH2 domain) and its analogs and kinetic studies on their E/Z isomerization. I am excited to join the Teunissen Lab, where I can merge my passion for organic synthesis with my interest in advancing medical research. In my current role, I am focusing on the synthesis of small-molecule PET probes and assisting in the development of nanotherapeutics aimed at prolonging allograft survival.
Ashwa Umran
Role: Research Assistant
Hi! My name is Ashwa, and I’m an undergraduate student at Hunter College pursuing a Bachelor’s degree in Biological Sciences and a minor in Chemistry. I’m currently a research Assistant in the Teunissen Lab at Mount Sinai, where I help with imaging-based studies focused on nanoparticle immunotherapies. I recently completed the Tiny Earth Antibiotic Discovery Program at Hunter, where I explored soil bacteria as a source for new antibiotics. I’m especially interested in the intersection of cancer biology, genetics, and translational medicine, and I’m excited to keep learning more about imaging and its role in advancing clinical research.
Laura Stewart
Role: Lab Manager
Hi, I’m Laura! I received my M.E. degree in Biomedical Engineering in 2025 from University College Dublin, Ireland. I am currently the Lab Manager and Research Associate in the Teunissen Lab, where I help support research operations, including animal studies, lab safety, and preclinical imaging. My background is rooted in medical device development, which makes me especially excited to expand into translational research and explore how innovative therapeutics can move from the bench to the clinic. I look forward to contributing to the lab’s efforts in developing novel nanotherapeutics and imaging strategies within such a collaborative environment.
