Fluid Dynamics and Mixing:
Understanding the fluid flow and its interaction with geometrical structures is critical in the design and performance optimization of chemical and biological synthesis and analysis systems. Computational modeling and experimental investigations are employed to a broad range of applied problems that require the manipulation of fluids, ranging from the optimization of mixing in microfluidic devices, to the fluid flow mapping in polymer extruders, and the development of efficient microreactors.

High-Resolution Imaging of Soft Matter Systems:
While electron microscopies have emerged as one of the most versatile tools in instances where extreme spatial resolution is required, their application is limited when the materials of interest are sensitive to electron beam damage. In these cases, in order to be imaged the samples have to undergo severe alterations including cryogenic or chemical fixation, to enable them to withstand the harsh conditions to which they are exposed while being imaged in electron microscopes. This work is focused on developing alternative strategies enabling high-resolution electron imaging of beam-sensitive soft matter materials without alteration.

Surface Physics:
Scanning probe microscopy is being used to examine nanoscale physics at surfaces. Surfaces are interesting because surface atoms do not have as many bonds as atoms in the bulk of a crystal, which can affect their properties, including magnetism and electronic conductivity. Further, the arrangement of atoms on a surface has profound implications for devices because how new atoms arrange on a surface can affect how abrupt an interface between two materials is or how ordered the next layer of atoms are. Of particular interest is: (i) How we can use surface structures to control self-assemble of nanostructures and molecules; and (ii) How do molecules diffuse and move across a surface? This experimental work is paired with computer simulations to better understand the physics of these surfaces.

Atmospheric Physics:

The Earth's atmosphere exhibits many different aspects of physics, ranging from radiative transfer to fluid dynamics and thermodynamics. Our group uses high-resolution computer simulations (LES), as well as observational data, to study atmospheric flow, in particular the turbulent structure of the atmospheric boundary layer and boundary layer clouds.
