Marina Katayeva

Chief Executive Officer /Co- Founder

In 2002 M. Katayeva and Dr. Igor Levitsky became founders of Emitech, Inc., a small high technology company for the development of innovative concepts in the field of nanotechnology and advanced optoelectronic materials. She successfully leads the team of Emitech since then and became a CEO of Levi Diagnostics, incorporated in 2019 as a subsidiary of Emitech.

Mrs. Katayeva manages all the Small Business Innovation Research (SBIR) government contracts, company’s activity with the Defense Contract Audit Agency (DCAA) and Defense Contract Management Agency (DCMA). Under her leadership, Emitech was awarded with eight Phase I and three Phase II by the SBIR/STTR contracts: MDA (Missiles Defense Agency), MDA Airforce, MDA/NAVY, US Army, and NSF (National Science Foundation).

Mrs. Katayeva works on establishing successful relationships with government agencies, private sectors, universities, and other technology companies to expand Emitech Inc.'s and Levi Diagnostics Inc.’s penetration into the nanotechnology market.

Mrs. Katayeva participates in several conferences and workshops related to Life science technologies, conferences/workshops/trainings to establish connections with potential customers and stay updated on current market trends.

Igor A. Levitsky

Ph.D. Chief Scientific Officer / Founder

Dr. I. Levitsky, has over 20 years of experience in technology development, device design, prototyping and testing for various applications in chemical/biosensing, material science, and nanotechnology. Dr. Levitsky is a founder of Levi Diagnostics, Inc. and its President. LEVI Diagnostics was created in 2019 as a subsidiary of Emitech, Inc. to work on development and commercialization of electrochemical biosensor-based device to provide non-invasive diagnostics and women’s health monitoring.

Due to the COVID-19 pandemic, Dr .Levitsky and his team refocus his effort to develop a device for detection of CoV-2 virus.

Dr.Levitsky had a Postdoctoral appointment at the Massachusetts Institute of Technology, Department of Chemistry, Cambridge, MA (1997-1999).

Dr. Levitsky was actively involved in R&D work, including SBIR program and private funding, when he worked as a Senior Scientist at the Altair Center (Shrewsbury, MA, 1999- 2001), Brown University (2001-2002) and as a Principal Scientist at Emitech, Inc. (Fall River, MA, 2002 - present). During this time, Dr. Levitsky as Principal Investigator had multiple

Phase I/Phase II awards (more than fifteen) from different government agencies such as NSF, DoE, DoD, DHS, and DoS.

Most of these topics were related to the study of organic/composite nanomaterials and applications of new scientific concepts to the development of novel chemical sensors and optoelectronic devices: optical/chemiresistive/capacitive/multi-parametric sensors to explosives, volatile organic compound, metal ions, chemical warfare agents and carbon nanotube-based photodetectors and solar cells.

Dr. Levitsky has over eighty publications in peer reviewed journals (two reviews), one book, and ten patents.

Jonathan A. Runstadler

Member of Scientific Board of Directors

PhD of Virology Tufts University

Professor Runstadler joined the Department of Infectious Disease & Global Health in 2017. Working at the host-pathogen-environmental interface, the Runstadler laboratory studies how emerging virus, specifically influenza, is maintained, transmitted and evolves in reservoir or intermediate animal hosts.

A major part of this work is directed at understanding how both host and viral factors may influence the risk of viral spillover into new hosts, including humans. Dr. Runstadler is working with collaborators to bridge the gap between studies of disease

surveillance and disease ecology with a molecular and comparative understanding of pathogenesis, immune response and evolution. Our current research is particularly focused on understanding genotype-phenotype relationships of the influenza virus, the role of diverse hosts and environments, and the interspecies movement of virus to the emergence of disease in new populations.
