Dr. Daniel K. Gladish, Professor of Botany and Director of The Conservatory
Dr. Dan Gladish was born and raised in Southern California. He graduated from San Gorgonio High School in San Bernardino, CA, then moved to North Hollywood. He studied music briefly at Long Beach State University in Long Beach, CA.
Prior to becoming a botanist Dan had careers unrelated to science. He spent 15 years as an entertainer, performing college concerts, nightclub and casino shows, and on TV. He played electric bass guitar, guitar, and trumpet; he sang, performed comedy, and was a master of ceremonies for The Rising Generation, Randy Sparks and The Back Porch Majority, The Bright Angel Band, and Terra Nova. He recorded four albums and contributed to three movie soundtracks produced by Walt Disney Studios. While with The Back Porch Majority he moved to Linden in Northern California where the band opened a nightclub called "Lloyd's of Linden."
When he decided to leave the music business, Dan worked for seven years as a farm hand, carpenter, and semi-truck driver (he logged over a million accident-free miles) while saving to return to college. He continued to drive semi-trucks on weekends and summers while an undergrad at the University of California at Davis, where he earned a Bachelor of Science degree in Botany.
As a graduate student, Dan served four years as a Teaching Assistant in the Department of Botany (now the Section of Plant Biology) at the University of California at Davis. He taught general botany, plant anatomy, and plant physiology laboratory classes. In addition to his dissertation research on the effects of temperature on root development, he did research on the modes of action of several herbicides and on the correlation of anatomical structure and performance quality in clarinet reeds. Just prior to completing his Ph. D. degree in plant biology, he moved to Hamilton, Ohio, to join the faculty of the Miami University Department of Botany.
As of 2011 Dan has 17 years experience teaching full time for the Miami University Department of Botany mainly at the Hamilton campus. He has taught Plant Biology (Bot 191) with an inquiry-based laboratory, Ecology of North America (Bot 171), Plants, Humanity, and the Environment (Bot 131), Cell and Molecular Biology (Bot 203, Zoo 203) and the lab (Bot 203L), and a seminar course with Prof. Bekka Eaton-Reardon on the concept of communities (BIS 301). Several Hamilton undergrads have completed independent study and independent research projects under his supervision. He co-advised a master's degree student who did work in restoration ecology. With a doctoral student and two masters students, Dan has been focusing on research in programmed cell death in plant roots. At The Conservatory, a living museum of exotic and Ohio native plants at the Hamilton Campus, Dan is supervising a program for 4th grade children in cooperation with the Hamilton City Schools.
He also plays electric bass, sings, and writes music for The Albrecht Music Venture.
Doctoral Dissertation: "The effects of temperature on the growth kinetics, morphology, anatomy, and physiology of pea (Pisum sativum L.) roots."
Current research projects
- The evaluation of newly discovered ultrastructural anomalies in root meristems of Zea mays var. amylacea.
- The effects of flooding on root systems of cool season legumes with an emphasis on the role of programmed cell death and its biochemical pathways and molecular regulation.
- A long-term study of secondary ecological succession at field sites with similar soil and environmental qualities, but different histories, the Miami University-Hamilton campus. This project involves undergraduates heavily.
- Management of a restored tallgrass prairie on an old landfill site at Hamilton Campus.
Past research projects
- Effects of chlorsulfuron and imidazolinone herbicides on roots of garden pea (DuPont Corp.).
- Mobility in soil of Metolachlor, a soil-based herbicide (for the University of California Extension Service and Syngenta).
- Phytotoxic side-effects of Lorsban insecticide on almond trees in N. California (for Seiferman Farms, litigants against Dow Chemical Corp.).
- The correlation of anatomy and playing qualities in performance-rated clarinet reeds (for R.J. Maier Products, Inc.).
- Effects of temperature on the development of root meristems, including the primary meristem and lateral root initiation.
