Chiara Mariottini, PhD – Research Assistant Professor, Project Manager

Chiara’s first interaction with research was during her undergraduate years at University of Perugia, in Italy, where she studied Medicinal Chemistry and Pharmacy. Towards the end of her undergraduate studies, she spent approximately a year in the Department of Pharmacology under the supervision of Dr. Carlo Riccardi and Dr. Maria Cristina Fioretti, both known as international experts in cell biology and immunology. It was during her tenure with them that she decided to pursue a career in science.Chiara then moved to Florence, where she specialized in behavioral neuroscience and neuropharmacology and obtained her PhD in Physiological and Nutritional Sciences (with specialty in Neuropharmacology) from the University of Florence. In January 2008, Chiara joined the Department of Pharmacology and Systems Therapeutics at Mount Sinai, New York, for her postdoctoral studies with Dr. Ravi Iyengar. Chiara’s research at the Iyengar Lab focused on the transcriptional mechanisms that can regulate memory strength, flexibility, and persistence in health and disease, with a particular focus on the hippocampus.

Throughout her career, Chiara’s interest in translational research and clinical development has grown considerably, and for this reason, Chiara joined the Krammer Laboratory in November 2018, as an Assistant Professor of Microbiology to work on developing a universal influenza vaccine, in collaboration with Dr. Palese and Dr. Garcia-Sastre. Outside of research, Chiara enjoys any outdoor activity, in particular running and hiking. Chiara loves dogs.

Meagan McMahon, PhD – Research Assistant Professor

Meagan received her undergraduate degree at Deakin University, where she majored in Biology. The following year, she completed her honours year under the guidance of John Stambas and Daniel McCulloch at the School of Medicine, Deakin University in Australia. During this honours year she assessed the role of ADAMTS enzymes in influenza virus infection. Meagan went on to continue studying the role of ADAMTS enzymes in influenza virus infection and immunity in the Stambas and McCulloch laboratories as a PhD student and graduated in 2017. Meagan’s current research interests include developing a universal influenza virus vaccine, assessing broadly protective monoclonal antibodies and researching influenza virus transmission in animal models.

Meagan is originally from Melbourne in Victoria, Australia. Here she enjoyed following the Collingwood Magpies, an Australian rules football team and being champion of board games, like Cyclades and Settlers of Catan.

Postdoctoral Fellows


Juan Manuel Carreno Quiroz, PhD

Juan Manuel obtained his Bachelor’s degree from the National Autonomous University of Mexico (UNAM), and then joined the Arias-Lopez group at the Institute of Biotechnology UNAM to obtain his Master’s Degree. He then pursued his PhD in Microbiology and Immunology at the ETH Zurich in Switzerland in the laboratory of Dr. Burkhard Ludewig, and during his studies he focused on the immune responses against Salmonella typhi and the development of vaccines against this pathogen. In the Krammer Laboratory, Juan Manuel oversees and manages the serology core, his work is focused on understanding the immune responses during viral infection and vaccination settings. Outside of the lab, he enjoys to run in central park, to participate in indoor sports, and travel around in his bike. He spends time with family and friends exploring all the culinary, cultural and amusement attractions in NYC.


Catherine Teo, PhD

Catherine received her Bachelor’s degree from the National University of Singapore where she specialized in Life Sciences and worked on Dengue Virus. She went on to pursue her PhD in Virology at the Imperial College London under the guidance of Peter O’Hare. During her studies she focused on the spatiotemporal analysis of de novo translation and transcription during Herpes Simple Virus infection by employing click chemistry. During her first postdoctoral fellowship she worked on the characterization of monoclonal antibodies against influenza virus, in particular the H5 and H7 subtypes. She also investigated Fc-mediated antibody effector functions and their in protection against influenza virus infection. Catherine’s current research interests include developing vaccines and antibodies against influenza viruses and emerging zoonotic viruses such as hantaviruses and arenaviruses. Outside of the lab, Catherine enjoys exploring the city and adventuring out into nature.


Isabel Francisco, DVM

Isa grew up in Manila, Philippines and came to the US to complete her undergraduate degree at Dartmouth College, where she majored in Biology and minored in English. She went on to receive her Doctor of Veterinary Medicine degree at the Cummings School of Veterinary Medicine at Tufts University. While in veterinary school, she completed an International Veterinary Medicine postgraduate certificate, volunteered for veterinary service trips in Morocco and the Dominican Republic, and worked on public health research in her home country of the Philippines. After receiving her DVM, she completed an equine medical and surgical internship at Vermont Large Animal Clinic and then worked for Health Resources in Action, a public health nonprofit in Boston. She is interested in working at the intersection between animal, human, and environmental health, and in public health work related to health and environmental justice.
