Leo's unique expertise in seismic research is in both ray theory as well as finite difference modeling. After completing his Ph.D. on earthquake hazard assessment at the California Institute of Technology, Leo joined Cambridge Schlumberger Research as a Senior Research Scientist for six years. There he worked on down-hole monitoring of micro-seismic events. In 2008, Leo joined Microseismic Inc. (MSI), where he led the Development department, focusing on surface monitoring of microseismicity, in the capacity of Senior Geophysicist and Chief Geophysicist. Until the end of 2017 Leo carried out research as the Purkyne Fellow at the Institute of Rock Mechanics and Structure within the Academy of Sciences of the Czech Republic.
Leo’s goal is to improve understanding of induced seismicity in general, as well as to help operators to understand and improve microseismic analysis in their reservoirs.
He is a member of the Seismological Society of America, Society of Exploration Geophysics, Society of Petroleum Engineering, the European Association of Geoscientists and Engineers, and the American Geophysical Union. He is an active participant in all of these societies, having organized special sessions, served as associate editor and editorial organizer of various journals, given many invited talks, and is an active reviewer of the latest research publications. Leo is a coauthor on 44 peer-reviewed papers, 15 business journals, 16 extended abstracts, and has received over 1000 citations in reviewed journals and books. Additionally, he is an author or coauthor on 10 patents and patent applications.
