  • Global environmental change

Professor Berhe's research is broadly focused on soil science and global change science. The main goal of her research is to understand the effect of changing environmental conditions on vital soil processes, most importantly the cycling and fate of essential elements in the critical zone. She studies soil processes in systems experiencing natural and/or anthropogenic perturbation in order to understand fundamental principles governed by geomorphology, and contemporary modifications introduced by changes in land use and climate.

Professor Berhe's general research themes are:

  • Effect of climate changes (specifically rainfall and temperature) on storage and stabilization of soil organic matter and cation nutrient budgets
  • Nano-scale biogeochemistry of iron oxides, especially how the size and concentration of oxides in soil control stabilization and destabilization of organic matter
  • Erosion and terrestrial carbon sequestration, specifically temporal evolution of the erosion-induced terrestrial carbon sink and reconstruction of environmental history from sediments
  • Political ecology of land degradation and ownership, particularly the contribution of armed conflicts to land degradation and ways people relate to their environment

Raymond Chiao

Professor Emeritus

rchiao@ucmerced.edu

Raymond Chiao is a professor jointly in the UC Merced schools of Natural Sciences and Engineering. Previously, he was a professor for 38 years at UC Berkeley, where he earned international acclaim (including the Willis E. Lamb Medal and the Einstein Prize for Laser Science) studying nonlinear and quantum optics. At UC Merced, is pursuing a new line of groundbreaking research on gravitational radiation.

Theoretical atomic and molecular physics.

Professor Cleary is interested in how complex tissues develop from relatively small populations of stem cells. Nervous system development in the fruit fly, Drosophila melanogaster, provides an excellent model system for studying this process. His lab focuses on how Drosophila neural stem cells, called neuroblasts, which produce the diversity of cell types found in the nervous system. His primary aim is to understand:

  • How cell fate decisions are temporally regulated, so that distinct cell types are made at specific times during development
  • How mitotic activity is regulated, so that neuroblasts stop and start dividing at the proper time
  • How cell fate information is passed from a neuroblast to its progeny and the role of chromatin remodeling factors and other transcription factors in this process

His research team uses the many powerful molecular and genetic techniques available for Drosophila research to address these questions, with the ultimate goal of identifying mechanisms that are conserved in human stem cells.

Michael E. Colvin

Professor and Associate Dean for Academic Programs

mcolvin@ucmerced.edu

The past century has seen tremendous progress in determining the biochemical and biophysical processes that constitute life. One exciting consequence of this understanding is the possibility of developing mathematical models of biological function that are accurate and even predictive.
Professor Colvin's research uses a wide range of simulation methods to model biological systems at different levels. Much of his research uses molecular modeling to study biochemical problems, with a particular emphasis on modeling the activity of DNA-binding food mutagens and anticancer drugs. These methods involve computing the structures and energetics of biomolecules using either quantum or classical mechanics, and often require the use of supercomputers.
Other molecular modeling projects include studying:

  • Synthetic analogs to nucleic acids and exotic nucleic acid structures
  • The function of DNA-processing multiprotein complexes
  • The mechanism of cytochrome P450 and other enzymes

More recently, his research interests have expanded to include simulations of biophysical and cellular processes using equations that describe the system as continuous (and sometime stochastic) dynamical systems. These projects include:

  • Simulating the formation mutagenic compounds during cooking
  • The operation of the nuclear pore complex
  • Cell fate decisions

These projects offer a wide range of research projects for students interested in the application of mathematics and computers to understand the living world.

Millions of species demonstrate that evolution happens, but few illuminate the process. Professor Dawson's lab focuses on elucidating the origins, maintenance, and loss of marine biodiversity, from molecular to ecosystem levels. His specific interests are:

 

  • How molecular variation explains and causes differences between individuals, populations, species, and higher taxa
  • How the environment shapes and is shaped by genetic, organismal, population, and community variation

His lab's work scales from micro- to macro-evolution and integrates biological and physical sciences. Topic areas include:

  • Adaptation, ecological genetics and evolutionary ecology
  • Population genetics, phylogeography, biogeography and phylogenetics
  • Speciation, systematics and taxonomy
  • Behavior and morphology
  • Climate change, invasive species and marine protected areas

Professor Edwards' research focuses on understanding how the environment affects the evolution of phenotype and behavior in reptiles. To do this, she incorporates ecological, genomic, behavioral and phenotypic information to look at:

  1. how the landscape affects evolutionary history;
  2. how shifts in ecological niche drive phenotypic evolution; and
  3. how ecological and sexual selection combine during speciation.

She is also interested in using integrative studies to inform conservation management strategies for endangered and vulnerable reptiles and amphibians.

Professor Forman's laboratory focuses on the molecular biology and biochemistry of signal transduction and cellular adaptation to reactive oxygen species and other electrophiles relevant to the response of the lung to environmental pollution.

Ajay Gopinathan

Professor Gopinathan's research focuses on a variety of problems in biophysics, soft condensed matter and the interface between the two fields. His group uses theoretical and computational techniques from different areas in soft matter and statistical mechanics including polymer physics, elasticity and anomalous transport.

The group's primary research area is Biological Transport which involves understanding how transport occurs in biological systems across different levels of organization and scale -  ranging from macromolecules and vesicles being transported within the cell and across membranes to cells to communities of cells and higher animals across geographical scales. In the cellular context, the environment is structurally complex and exhibits unique dynamical properties. This results in novel types of transport phenomena and effects that in vivo systems manage to remarkably exploit. Examples include polymer transport across membrane pores, macromolecular transport through nuclear pores and motor driven intracellular transport. At higher levels, problems studied include eukaryotic cell motility, bacterial community motility and foraging in higher animals.

In addition, his group is involved in a number of other projects including drug design, colloidal dynamics, self-organization at surfaces, the geometry and dynamics of elastic sheets, transport in disordered systems and fluctuation induced forces.

Professor Kelley's research group uses ultrafast optical spectroscopy to examine the optical and electronic properties of semiconductor nanoparticles. He focuses on layered semiconductors - specifically gallium selenide and indium selenide - which have layered crystal structures and form two-dimensional, disk-like nanoparticles. The optical properties of indium selenide are very well suited for the absorption of sunlight; therefore, its nanoparticles hold considerable promise as the active media in photovoltaics.

Professor Kelley's group synthesizes nanoparticles that have diameters from 2 nm to tens of nanometers -  all of which are four atoms thick -  as the properties of such nanoparticles are strongly size dependent, due to quantum size effects. He is primarily interested controlling  and optimizing the properties of the nanoparticles for solar energy conversion.

Professor Kelley's research uses the laser light scattering techniques of resonance Raman and hyper-Raman spectroscopy to study the atomic-level details of how materials interact with light. These studies reveal the detailed mechanisms of fast photochemical reactions such as those involved in human vision, photography, xerography, and solar energy conversion. Her group carries out experiments and also develops theoretical and computational tools for analyzing the data.  Currently, her work focuses on using these techniques to understand how the vibrations (phonons) of semiconductor nanocrystals influence and are influenced by, absorption and emission of light in these materials.

The rising and setting of the sun causes dramatic oscillations in light and temperature each day. Most life forms involuntarily coordinate their lifestyles to these cyclic variations by means of an endogenous clock called the circadian clock. These circadian clocks have been identified in diverse organisms from cyanobacteria to humans, and studies suggest that the circadian clock has adaptive value.

Professor LiWang's laboratory is resolving the structural and biochemical basis of rhythmicity of the cyanobacterial circadian clock. The central oscillator of this clock is composed of only three proteins, which by themselves in a test tube with ATP generate a self-sustained circadian rhythm for several days. Their objective is to develop a comprehensive understanding of how a simple mixture of three proteins keeps time.
