Dr. Datta’s primary research interest lies in the application of plant biochemistry, genetics, molecular biology and microbiology in solving environmental problems,using phytoremediation, plant-microbe interactions and bioremediation. Dr. Datta’s research involves the study of interactions between plant, soil, microbial and water systems to understand the mechanisms of uptake and detoxification of specific environmental contaminants in biota from two broad angles – biochemistry and genetics.
Specifically, Dr. Datta’s current research focus is on the study of bioavailability of metal and organic contaminants in aquatic media and the potential of using plants to remediate contaminated sites, mediated by microbes. Dr. Datta actively collaborates with environmental . . .
In multicellular organisms, how do multiple cell types originate from one cell and one genome? A critical early cell fate decision is whether to develop as germline (reproductive) or soma (non-reproductive). My research focuses on assessing how the highly conserved DREAM transcriptional repressor complex maintains the germ vs. soma cell fate decision during embryogenesis. After a flurry of cell divisions from the starting “germ cell” (i.e. united egg and sperm), somatic cells begin to exit the cell cycle as the DREAM complex suppresses the proliferative germ cell program. This process is commonly reverted in cancer cells (i.e. a soma-to-germline transition) and is . . .
Our work is centered on the cell wall and associated extracellular polymers of algae. We are interested in what these algal extracellular matrices can tell us about: 1) the evolution of the land plant cell wall, 2) the unique characteristics that allow for life in aquatic habitats, 3) the interactions within complex biofilms, including the heterotropic utilization of complex macromolecules, and 4) the biomineralization processes (ex. silica and calcium carbonate) associated with these extracellular polymers.
What is the broader significance of our work? The characters of plant cell walls determine the properties of innumerable products we consume every day. Our work has potential . . .

Broadly speaking I am an evolutionary ecologist who studies how plants interact with their abiotic and biotic communities. My work integrates the theory and techniques from the disciplines of ecology, evolution, genetics, chemistry, and physiology. My research makes both fundamental and applied contributions and current projects include:
- deciphering the interplay between the abiotic environment (especially nutrient eutrophication and water availability), the genomic structure (genome size and composition) of terrestrial plants, and multitrophic communities (plants, herbivores, pathogens, pollinators),
- examining the efficacy of management efforts and the cultural, social, and ecological impacts of invasive plant (e.g., baby’s breath, Eurasian milfoil) and/or insect (e.g., Spotted winged drosophila on soft . . .
Research conducted by my lab group is focused on ecology and restoration in aquatic systems including lakes, streams, coastal wetlands and the riparian ecosystems that connect them. The research that my graduate students, our collaborators and I conduct tends to focus on ecological patterns and processes in systems influenced by human actions. In many cases we apply the learned scientific understanding to inform the restoration or rehabilitation of the system or population. Our projects are often motivated by this reciprocal interplay and exchange between restoration and the advancement of scientific understanding. Major projects have/are conducting examine 1) the ecology and restoration of . . .

I am a plant molecular biologist who is interested in understanding of how trees make cellulose. Simply put, cellulose is a chain of glucose molecules, and a large number of such cellulose chains weave together with other polymers to form plant cell walls. Cellulose biosynthesis is also one of the most ancient and essential life processes of plants.
Due to its omnipresence in terrestrial ecosystems, we use a large number of cellulose products in our day-to-day life in the form of paper, furniture, clothes, medicines and even food. Ironically, we knew little about how plants synthesize cellulose until recently. However, the last decade . . .

I am an ecosystem ecologist with interests in energy and biogeochemical cycles in freshwaters. My research program blends basic and applied research, and integrates across aquatic habitats including stream, river, wetland, lake littoral zones and the nearshore regions of the Great Lakes. My past and future research trajectory is governed by an interest in understanding the role of small, poorly quantified fluxes or perturbations on ecosystem processes, and in linking those ecosystem processes to the underlying structure of microbial, algal, macrophyte and animal communities.
One benefit of an academic career is the synergy between an active research program and undergraduate and graduate . . .

- The Laboratory of Cancer Metabolism and Functional Genomics is to characterize deregulation of cancer metabolism and the role of nutrients during cancer initiation and progression. In this perspective, we are aiming to understand the underlying mechanisms and pursue alternative and feasible means to apply on patients. In addition, understanding of diet-cancer interactions could establish a strategy for long-term cancer prevention.
Diabetes is caused by either the loss of the insulin producing beta cells in the pancreas, leading to a deficiency of insulin (type 1 diabetes), or insulin resistance, reduced insulin sensitivity, and reduced insulin secretion (type 2 diabetes). In both types of diabetes, the patients develop serious secondary complications, such as microvascular complications, oxidative stress and endothelial dysfunction, cardiovascular disease, and kidney failure.
MicroRNAs (miRNAs) are newly discovered, 21-24nt in size, non-coding RNAs. miRNAs negatively regulate the expression of protein-coding genes by binding to the 3'-untranslated region (3'-UTR) of specific targeted gene transcripts (mRNAs). Each miRNA regulates the expression of hundreds of target . . .

I am an environmental microbiologist who studies microbial communities in diverse ecosystems. Microbes (Bacteria and Archaea) are ubiquitous in the environment and play essential roles in the cycling of elements. These environmental microbes are capable of catalyzing a wide array of chemical reactions, many of which may have industrial applications. I study how complex microbial communities can cooperate to perform functions of industrial interest. The majority of microbes in the environment are difficult to grow in the lab. Furthermore, many industrially-relevant pathways are found in microbes not yet grown in the lab. I seek to employ both culture-based and culture-independent . . .

Dr. Werner became interested in the question “What is life?” as a four-year old child in his parent’s garden in former East Germany. With the age of 10, he began to develop a life-long interest in the biology of butterflies and moths. He has been breeding and collecting them ever since. For his Master’s thesis, he decided to shift his focus to molecular biology because this was a newly emerging field of biology that promised new jobs.
Thus, Dr. Thomas Werner studied the human heart disease-causing virus Coxsackie B3 at the molecular level at Friedrich-Schiller-University Jena in Germany. After the fall of the Berlin . . .
