Krzysztof Bąk serves as a Professor within the Faculty of Geology at the University of Warsaw, maintaining active research output through 2023. His scholarly work centers on Mesozoic geological processes in the Tethyan realm, with particular emphasis on Carpathian Basin evolution during Jurassic and Cretaceous periods. Professor Bąk's primary research domains include Paleontology (specializing in radiolarians and microfossil assemblages), Geochemistry (stable isotope analysis and organic geochemistry), Sedimentology, and Stratigraphy. His investigations frequently address Oceanic Anoxic Events, sea-level fluctuations, redox condition variations, and paleoenvironmental reconstructions in deep-water settings. Notable contributions include deciphering the timing of sponge spicule redeposition events and organic matter accumulation patterns linked to global climate shifts. Analysis of his 15 most recent publications reveals methodological integration of micropaleontological, geochemical, and sedimentological approaches to reconstruct Western Tethys paleoenvironments. Key thematic threads include Cretaceous biostratigraphic correlations, Jurassic-Cretaceous transition dynamics, and Carpathian Basin depositional histories. His work demonstrates consistent collaboration with Maria Bąk and Zbigniew Górny across high-impact journals like International Journal of Coal Geology and Geological Society of America Bulletin , alongside contributions to Poland's Detailed Geological Mapping program. Professor Bąk extends his expertise beyond traditional research through geotourism applications, notably examining cognitive and educational aspects of geological heritage sites in the Tatra Mountains. His publication record indicates sustained research leadership within the Faculty of Geology, with no evidence of reduced activity or emeritus status.

Daniel Lehrmann serves as the Gertrude and Walter Pyron Professor in the Geosciences Department at Trinity University, where he teaches paleontology, sedimentary geology, basin analysis, and field geology courses. Originally from Wisconsin, he earned his B.S. and M.S. from the University of Wisconsin system before completing his Ph.D. at the University of Kansas. His research program focuses on marine sedimentary basin evolution, carbonate platform development, Earth's chemical and biological system changes, diagenetic processes, and mass extinction events. Lehrmann employs a comprehensive methodological approach including field work, satellite image analysis, GIS, petrography, geochemistry, biostratigraphy, and forward stratigraphic modeling. His fieldwork spans the Nanpanjiang Basin in south China, additional Chinese basins, and global sites including Indonesia, Japan, Turkey, Saudi Arabia, Italy, Mexico, the Gulf of Mexico, and central/western Texas. Lehrmann's recent publications reveal strong trends in Triassic carbonate platform evolution, Permian-Triassic boundary events, microbialite formation, and advanced analytical techniques including machine learning applications in carbonate petrography. His work demonstrates interdisciplinary integration of paleontology, sedimentology, geochemistry, and structural geology to address fundamental questions in Earth history. Erasmus Haworth Distinguished Alumni Honors in Geology Award from the University of Kansas SEPM best paper award Honorable mention for best paper in Palaios Lehrmann has co-advised graduate students at Rice University, Stanford University, the University of Alabama, and UTSA, while securing over $2 million in external funding from NSF, ACS Petroleum Research Fund, Fulbright Program, and oil companies over 25+ years. He serves as associate editor for the Journal of Sedimentary Research and AAPG Bulletin, and actively participates in geological organizations including the Geological Society of America, Southwest Research Institute, Edward Aquifer Authority, and Witte Museum. Lehrmann also provides geological support for UNESCO World Heritage sites in China and promotes AAPI diversity initiatives through the EAST executive committee.
