Person

Douglas Gordon Hayes, PhD, MBA

Institute Professor | Biosystems Engineering and Soil Science
Overview

My research program focuses upon two areas. First, we are researching the sustainable use of plastics in agriculture. Specifically, we are investigating the use of biodegradable plastics as mulch films for vegetable production and their long-term impact on agricultural ecosystems, including the fate and transport of micro- and nanoplastics. Second, we are studying the use of surfactant self-assembly systems, particularly microemulsions, for drug delivery and for separation and purification. Both research areas involve the use of small-angle x-ray and neutron scattering.

Research Focus

Agricultural plastics, biodegradable polymers, micro- and nanoplastics, biobased surfactants, surfactant self-assembly systems

Courses
Below are courses taught during the current or past three academic years. Consult Timetable for the most current listing of courses and instructor(s).

BSE 231 - Biochemistry for Engineers
3 credit hour(s)

Fundamentals of biochemistry presented from an engineering point of view and applied to solve engineering-related problems. Topics to be covered include fundamental organic chemistry of amino acids, carbohydrates, lipids and other important biochemicals; the role and control of pH in biological solutions; fundamental biochemistry of proteins and enzymes; introduction to bioenergetics and metabolic pathways, and the replication, transcription, and translation of DNA.

(RE) Prerequisite(s) : CHEM 122* and CHEM 123*, and MATH 132* or MATH 141*.

BSE 321 - Biothermodynamics, Heat, and Mass Transfer
3 credit hour(s)

Application of thermodynamics to biological systems; heat transfer with emphasis upon conduction and convection applications; introduction to diffusion mass transfer.

(RE) Prerequisite(s) : BSE 221.

BSE 530 - Research Problems in Biosystems Engineering
1 - 3 credit hours

Theoretical and experimental studies relating to current problems in biosystems engineering.

Repeatability: May be repeated. Maximum 6 hours.

Other Instructors: Gan, Hao | Yoder, Daniel
