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.

Associate Scientist


Veronika Chromikova, PhD

As a kid, I could never make up my mind whether I wanted to be a scientist, a doctor, a ballet dancer, or a writer. However, when my sister took me to a biology lab and showed me how to plate bacteria for the first time, the decision has been made.  I finished my Bachelor’s degree in Biology (2008) and Master’s degree in Molecular Biology (2010) at the Comenius University in Bratislava (SK). During my Master’s Degree research, at the Institute of Molecular Biology at The Slovak Academy of Sciences, I studied how individual proteins interact in a bacterial spore coat during the process of sporulation. I earned PhD in Biotechnology (2015) from the University of Natural Resources and Life Sciences in Vienna (AT) where I worked with mammalian cell culture and established stable cell lines for production of recombinant IgMs.  Part of my PhD studies was done at the University of California Irvine, in Dr. Forthal’s lab, focusing on HIV research – where I discovered the charm and treachery of immunological assays, and at the Technical University in Munich in the lab of Dr. Groll, focusing on X-ray crystallography – where I realized that sometimes your plans to crystallize a protein may be just a wishful thinking. Outside of the lab I like driving, reading and videogames and contrary to the general belief of my colleagues, I spend some time outdoors occasionally.

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, where he had the opportunity to explore the fascinating world of viruses studying the restriction of rotavirus by interferons. 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. With the keen interest of reincorporating to the virology field, Juan Manuel recently joined the Krammer Laboratory and is currently working on understanding the mechanisms of immunological imprinting during influenza virus infection. Outside of the lab, Juan Manuel enjoys to run in central park, participate in indoor sports, and to travel around in his bike. He spends time with family and friends exploring all the culinary, cultural and amusement attractions that this great city has to offer.

Daniel Stadlbauer, PhD

Daniel received both his Master’s Degree and Doctoral Degree from the University of Natural Resources and Life Sciences, Vienna. Daniel undertook his doctoral studies as a visiting student in the Krammer Laboratory and was interested in investigating countermeasures against emerging avian influenza subtype H7N9 viruses, allowing him to gain insights into H7N9 vaccine design.

In 2019, Daniel joined the Krammer Laboratory as a postdoctoral fellow. His current research interests include investigating the influenza virus neuraminidase as a vaccine antigen, characterizing anti-neuraminidase antibodies and aiding in the development of a universal influenza vaccine candidate. Additionally, Daniel is overseeing and managing the influenza serology core in the Krammer Laboratory.
