Current Position

Independent Research Scientist, with his own group, within the Laboratory of Molecular Ecology of Vectors & Pathogens, Institute of Parasitology, BC, Academy of Sciences of the Czech Republic.

Research centered on adapting and developing genetic methods to understand the evasion strategies used by various European species within the Borrelia burgdorferi sensu lato complex, the causative agent of Lyme disease, and identification of new, common antigenic markers that could be used for detection purposes. Also investigating the the transmission dynamics of the old world relapsing fever borrelia using the tick-animal model.

Was involved in the FP7 proposal HEALTH – ANTIDotE consortium for the identification and evaluation of tick vaccine candidates (2013-2018).


Postdoctoral Experience

May 2007 – April 2012 – Visiting fellow, Laboratory of Zoonotic Pathogens, Rocky Mountain Laboratories, NIAID, NIH, Hamilton, Montana

Apr 2006 – April 2007 – Postdoctoral Fellow, Laboratory of Molecular Biology of Vectors and Pathogens, Institute of Parasitology, Biology Centre, ASCR, Ceske Budejovice, Czech Republic


Educational Background:

Univ. of South Bohemia, Czech Rep.          Ph.D. Genetics & Mol. Biol.         2000–2005

  • Identified and sequenced, using a bioinformatics approach, phylogenetically conserved innate immune proteins from hard and soft ticks including defensins, integrins and lectins.
  • Localized and sequenced the first hemolymph lectin, possessing a fibrinogen domain, from a tick and involved within the tick innate immune system.
  • Comparative analyses using phylogenetic methods were done to understand the evolution of such proteins.
  • Supervisor – Prof. Vaclav Hypsa, Specialist Advisor – Prof. Libor Grubhoffer

Univ. of the West of England, U.K.                   M.S. Biotechnology                 1994–1995

  • Studied mixed trypanosome infections in different species of tsetse flies. Statistically identified the possibility of competition among trypanosomes within the midgut and at the time of maturation within the salivary glands.
  • Supervisors – Dr. Sue Welburn & Dr. Ian Maudlin (Present address: Univ. of Edinburgh)

St.Joseph’s College of Arts&Sc.(B.U.), India   B.S. Microbiology                    1990–1993
