Dr. Ana Martin-Ryals

Assistant Professor and Biological Engineering Undergraduate Coordinator
Specialization Areas: Environmental Biotechnology, Resource Recovery, Life Cycle Assessment

Dr. Ana Martin-Ryals is an Assistant Professor and Undergraduate Coordinator in the Agricultural and Biological Engineering department at the University of Florida. The broad aim of her research program is to develop innovative waste and wastewater treatment processes that can enhance sustainability within water-energy-food systems. Organic wastes streams including municipal wastewater, animal manure, and food waste, among others, represent a substantial and underutilized set of feedstocks for bioenergy and biomaterials production. Dr. Martin-Ryals is working to develop treatment systems that can recover the carbon, water, and nutrients contained in these waste streams to produce value-added products such as renewable energy, reusable water, biobased fertilizers, and bioplastic.

In her research, Dr. Martin-Ryals works extensively with a process called anaerobic digestion. Anaerobic digestion utilizes microbes to convert organic material into methane-rich biogas. The biogas can be used as an alternative to natural gas for heat and electricity production, or leveraged to produce other biobased chemicals or materials. Dr. Martin-Ryals’ previous and on-going research includes advancing anaerobic membrane bioreactor (AnMBR) technology, microbial community analysis, hydrothermal liquefaction biofuel production, nutrient recovery from wastewater, bioplastic production from food waste, and life-cycle assessment to evaluate environmental impacts of different waste treatment strategies and technologies. Dr. Martin-Ryals is also involved in engineering education research and improving undergraduate STEM education.
