Welcome.
You may be wondering about my somewhat complicated Family Name, its origin, and how to pronounce it. For an explanation, please click here
Here is the Obituary of J. A. Gy. E. Mojzsis Mojsvari (a.k.a. Edmund V. Mojsisovics), born October 18, 1839. died October 2, 1907. click here
The research carried out in my group is field- and laboratory-based, and seeks to understand such things as:
(i) How the surface state stabilized after planetary formation, to the time of the establishment of a permanently-oxygenated atmosphere;
(ii) When habitats for early life could have developed and the geophysical regimes that permitted the origin and proliferation of biological systems;
(iii) How the geomicrobiology of contemporary microbial communities provides some insight into the nature of the dominant biome(s) on the young Earth;
(iv) What information is preserved through physical/chemical changes endemic to high-grade metamorphic terranes; and
(v) What these results from the ancient rock record might mean in terms of the very establishment of habitability for Earth-like planets.
As a geologist, I view Earth as an accessible laboratory that serves as the natural baseline in the test for models to be used in search for ancient biospheres on other ancient planetary surfaces.
Below, you will find information about me and the activities of my research group and collaborators.
