Dr. Jonathan M. Husch received his doctorate in geology from Princeton University in 1982 and currently holds the rank of Professor of Geological and Environmental Sciences. A member of the Rider faculty since 1980, he was appointed GEMS Chair in 2006. Jon's Ph.D. dissertation was a comprehensive study of the petrogenesis and evolution of Palaeozoic anorthosites and related rocks associated with subvolcanic ring complexes, Air Massif, Republic of Niger.

Kathleen Browne
Associate Professor
SCI 320A

Dr. Kathleen M. Browne received her Ph.D. from the University of Miami in 1993 and currently holds the rank of Associate Professor in the Department of Geological, Environmental and Marine Sciences. Her Ph.D. thesis investigated the processes controlling the formation of lamination in Bahamian cyanobacterial mats and mounds known as stromatolites. Kathy's research interests focus on the interaction of sedimentological, biological, and chemical processes producing cyanobacterial mats in subtropical, carbonate environments in the Bahamas and Australia.

Reed Schwimmer
Associate Professor
SCI 323E

Dr. Reed A. Schwimmer, a 1984 Rider geosciences graduate, received his M.S. degree in geology from Bryn Mawr College in 1986 and his Ph.D. in geology from the University of Delaware in 1999. Reed currently holds the rank of Associate Professor of Geological and Marine Sciences. Reed has a broad background in the Earth sciences, particularly in coastal geology and geomorphology. Reed's primary research focuses on the development and evolution of coastal salt marshes and barrier islands in New Jersey, and elsewhere along the Atlantic coast.

Gabriela Smalley
Associate Professor
SCI 323A

Dr. Gabriela Smalley received her Ph.D. in marine and estuarine environmental sciences from the University of Maryland in 2002. She currently holds the rank of Associate Professor of Geological and Marine sciences. Before joining the department in 2004, she held a postdoctoral position at the Georgia Institute of Technology’s Chemical Ecology Laboratory in Savannah.
