My goal is to teach students the scientific method by hands-on experimentation. My objectives are to develop a new research-based laboratory course to give students the opportunity to experience how science is done through the practice of experimental inquiry. In my new lab course, students will be immersed in a dynamic project-based research environment by participating in experimental projects directly linked with ongoing faculty research covering a broad range of methodologies in molecular and cellular biology, bioinformatics and genomics.


To manage a network of populations within a species, we must understand the biological processes that interconnect populations, such as dispersal, and those that cause them to diverge, such as local adaptation along environmental gradients. Many organisms that inhabit estuaries disperse as microscopic larvae in patterns and at scales that have been difficult to discern. We are using genetic markers in several co-distributed coastal species to measure gene flow within and among Florida's Atlantic coastal lagoons.


Heavy metal detoxification in cells is contingent upon chelation of heavy metals within the cytosol by specific cellular ligands and transport of ligand-metal complexes, either across plasma membranes (elimination) or across intracellular membranes (sequestration and compartmentation). We aim to identify the transport proteins in the model plant Arabidopsis thaliana that are responsible for the sequestration of heavy metals and their chelates into a specific subcellular compartment, the vacuole.


In basic research, we are studying hearing in yellow fever mosquitoes in an effort to better understand the mating behavior, and therefore to control it.\nIn teaching, we are developing novel teaching materials for biology and mathematics courses using bioacoustic materials as "hooks" to engage student interest.


The objective of this project is to describe the molecular and cytological progression of bovine spermatogenesis in vivo and in vitro to provide fundamental basis for enhancing sperm production, clinical intervention in male factor infertility, and genetic modification of the male germ line.

Sirex woodwasp, an aggressive species with wood boring larvae, is known to kill pines in the southern hemisphere. It has been introduced to North America and was first collected in 2004 in New York state. We are investigating the potential use of a biological control agent that has proven very effective in the southern hemisphere, with particular emphasis on the potential for non-target effects. We are also investigating the associations between the white rot fungal symbiont of Sirex and native North American Sirex.


The Milk Quality Improvement Program (MQIP) utilizes a voluntary shelf life (VSL) program to analyze the sensory, chemical, and microbiological characteristics/profiles of dairy products manufactured in New York State. This program is designed to evaluate the overall quality and shelf life of grade A dairy products and to encourage and provide support to dairy plants to maintain and improve product quality.

2007 to 2013

Invasive species pose a serious threat to the ecological integrity of our land and water resources, agricultural products, and human and livestock health and well-being, causing billions of dollars a year worth of damage and threatening public health and safety.


Our research has revealed a universal mechanism by which crops and other plants regulate the senescence processes. Briefly, we have identified a master regulator of senescence, and based on this discovery, we have developed a technology for manipulating senescence in plants for significantly enhanced crop yield and improved postharvest performance of horticultural crops.

2007 to 2010

The McKnight Foundation has provided long-term grant support to the Ethiopian Agriculture Research Organization and Cornell to help develop the resources necessary for tef to benefit from the revolution in biotechnology. Comparative mapping combined with our recent trait mapping research has now positioned us to help our Ethiopian collaborators implement marker assisted breeding to enhance the rate of tef improvement.
