Curriculum Vitae 


Research interests: I study spatial self-organization and emergent properties of ecosystems at multiple scales. Two general questions of interest are:

  1. How do local interactions among ecological agents give rise to emergent patterning and properties at the landscape scale?

  2. How does geomorphic evolution of landscapes interact with biological evolution of organisms at the time scale relevant to both processes?

 

I am particularly interested in developing general theoretical frameworks to understand how an ecosystem works. The primary approach applied is mathematical modeling, combined with monitoring and/or experimental data collected from the field.

ResearchGate

Research Interests: My general area of research focuses on understanding the influences between localized bathymetry and the surrounding water column. As much of this work is on a scale logistically difficult (e.g. large scale shorelines) or impossible (e.g. under-ice) to survey with traditional techniques, I have worked since 2006 with Autonomous Underwater Vehicles (AUVs) as data collection platforms to further my research. My research aim is to continue developing an engineering research group with these vehicles and other emerging technologies to address pioneering scientific questions. The aim requires expertise in varied domains including: (i) environmental fluid mechanics; (ii) bathymetric mapping; and,(iii) invasive species identification and ecosystem assessment. Bringing together these diverse fields, enables an understanding of aquatic habitat and ecosystem assessment not previously available.

Curriculum Vitae

ResearchGate

Research Interests: My research is in coastal oceanography and ecology, specifically field-based study of water motion and the associated transport of water-borne material. This includes oceanographic study of bays in upwelling regions (open and enclosed bays), small "west coast" estuaries characterized by arid summers, bar-built mouths and pulsed winter inflow, and nearshore circulation (e.g., outflow from rivers, shoaling internal tides, and wind/wave-driven flows). My interest in environmental and ecological issues include larval/juvenile dispersal, coastal water quality (e.g., beach pollution), and primary productivity (including harmful algal blooms). My long-term goal is to better understand coastal ocean systems – to obtain an integrative view of how the diverse components, processes, and scales fit together.

Research Interests: My research interests include environmental turbulent flows as found in rivers, lakes, and the atmosphere with a focus on water-land-atmosphere interactions. Investigating surface exchanges of mass and energy improves our understanding of evapotranspiration, microclimates, turbulence intensity, and the transport of greenhouse gases or environmental pollutants. I use field investigations, laboratory measurements, and numerical simulations to investigate fundamental turbulent transport dynamics, enhance model development, improve forecasting capabilities, and inform resource management strategies, with a focus on mountainous regions, urban areas and the transitional zones between them.

Curriculum Vitae

Website

Research Interests: My research focuses on earth-surface processes (geomorphology) applied to a broad range of problems. Much recent work involves rivers, fluvial geomorphology, flood hydrology, floodplains, and watersheds. My research group applies fluvial geomorphology, hydrologic and statistical tools, hydraulic modeling, and other approaches to assess river dynamics and flood hazards. Although much current research focuses on rivers, I continue to work on a broad range of processes that shape the earth surface and operate, in particular, over anthropogenic time scales (yes, the "Anthropocene"). One pressing human application is for managing risk from natural hazards, and my group has worked extensively on quantifying those risks, guiding mitigation and other solutions, and providing a scientific basis for sound natural-hazards public policy.

Assistant Professor of Atmospheric Sciences

Curriculum Vitae

Research Interests: My research is to develop a unified understanding of how the tropical atmosphere works, and the key is to understand moist convection—cumulus clouds and thunderstorms. Moist convection dominates vertical energy transport in the lower atmosphere, and its interaction with atmospheric circulations forms the basis of a spectrum of atmospheric phenomena across wide temporal-spatial scales. I am now thinking about the following questions that help advance our understanding of multiscale convection. How do mesoscale [O(100 km)] cloud systems cluster together? What sets the propagation speed of synoptic scale [O(1,000 km)] tropical waves? What is the nature of the planetary scale [O(10,000 km)] Madden-Julian Oscillation (MJO)?

Research Interests: My research interests focus on integrating the traditional fields of stream hydrology, fluvial geomorphology, and stream ecology in the river environment. This includes research that applies understanding of ecological processes to managed river systems in an effort to improve their functionality and resiliency while continuing to provide the ecosystem services upon which we rely. I work closely with researchers from government agencies, NGOs, and other academic institutions on topics such as environmental flows, regulated river management, and stream restoration.  My research interests also include freshwater conservation in headwater systems, including studies on the hydrogeomorphic processes within montane meadows and the impacts of restoration actions on native species habitat.
