Publications and CV

My work investigates the effects of clouds on aerosol size distributions: 1) cloud processing and 2) wet scavenging. One application of this work is an improved representation of these processes in global climate and air quality models since these effects strongly control global aerosol distributions.

I am currently using a global model to study the effect of secondary organic aerosols on global aerosol size distributions. I am exploring the condensational behavior as well as the amount of secondary organic aerosol available. I am also exploring how anthropogenic changes in secondary organic aerosol between past and present climates influences aerosol size distributions.

Dr. Robin Stevens

Research Scientist
Ph.D. student (2009-2014), Dalhousie University
Department of Physics and Atmospheric Science

B.Sc., Physics and Applied Mathematics (Honours), Memorial University, 2007

Now a postdoctoral fellow at Leeds University, UK

I explored aerosol formation, growth and evolution in coal-fired power-plant plumes. These near-source aerosol processes are poorly represented in models used for evaluating the aerosol effects on clouds and climate. Furthermore, these aerosols also have a large impact on human health.

Ph.D., Physics, Atmospheric Science, University of Helsinki

I mostly specialize in data analysis of measurement data. Previously, my focus was on ion-induced nucleation, and nucleation in general. During my post-doc I intend to look into aircraft measurements of aerosol, cloud and precipitation properties and draw links between them.

Sal Farina

Scientific programmer, Colorado State University
Department of Atmospheric Science

B.Eng., Chemical Engineering, The Cooper Union
M.S., Chemical Engineering, Carnegie Mellon University

Sal is currently working on an overhaul of the GEOS-Chem with TOMAS aerosol microphysics modeling software. His efforts are targeted toward three goals:
- modernize GC-TOMAS to take advantage of distributed/parallel computing technology
- update GC-TOMAS source paradigms to encourage parallel development alongside the Geos-Chem core development.
- simplify the process of obtaining and using the many versions of GC-TOMAS
Fulfilling these goals will ensure that GC-TOMAS remains a state of the science tool and will encourage wider use in the scientific community.
