RESEARCH
The “cloud problem”, i.e., the understanding of the microphysical, dynamical and radiative processes that act at the cloud scale and their accurate representation in numerical models is the central theme of my research. My research focuses on processes such as precipitation initiation in liquid and ice water clouds (e.g., drizzle formation), the role of turbulence and entrainment in cloud evolution, mixed-phase clouds, the cloud-aerosol interaction, and the raindrop size distribution evolution under the action of vertical drafts and evaporation. I’m interest in the evaluation cloud parameterization in cloud resolving models (numerical models (e.g., ECMWF) using long-series of cloud and precipitation observations and the use of cloud parcel models, 2-D and 3-D turbulence models and Large Eddy Simulations models for the study of boundary layer clouds. Synergetic remote sensing observations from both space-based and ground-based sensors and their clever use through the development of new inversion algorithms and adaptive sampling strategies constitute my approach for probing clouds and precipitation in their natural environment. As part of my research I use a wide variety of observational platforms, however, millimeter wavelength radars are my primary observing tool for diagnosing the structure, kinematics and microphysics of clouds and precipitation
I am an international leader in the application of short wavelength radars for cloud and precipitation research from ground-based and space-based platforms. I have published over 80 scientific articles in peer-reviewed literature in the areas of millimeter wavelength radar research, cloud and precipitation physics. I have established a dynamic research program with funding sources well distributed between Canada, USA and Europe. Our research group participates in international field experiments. I have established strong, long-term research collaborations with the Atmospheric Science Division at Brookhaven National Laboratory, Upton NY and the DOE Atmospheric Radiation Measurements (ARM) program, the Division of Meteorology and Physical Oceanography at the University of Miami, Florida and the Institute of Geophysics at the University of Cologne, Germany. I am a member of the Mission Advisory Group and algorithm development team of the European Space Agency Earth Clouds Aerosols Radiation Experiment (EARTHCARE) Explorer Mission that is scheduled for launch in 2016. I am also a participant in several international satellite mission concepts (e.g., SnowSat, Polar Precipitation Mission, StormSat) proposed to space agencies in Canada, USA and Europe.
SERVICE
Served as a member at the National Science Foundation Engineering Research Center (40 million $US for ten years) for the Collaborative Adaptive Sensing of the Atmosphere executive committee that studies a paradigm shift in the way we observe severe weather near the ground using networks of short-range weather radars. Served for three years (2007-2009) as Associate Chief Scientist for the US DOE Atmospheric Radiation Measurements (ARM) program, the largest climate research program in the US with an annual budget of $US 65 million that funds 350 scientists and engineers. During my appointment I contributed in the area of cloud and precipitation observations, the interface of models with observations and the development of ARM collaboration with other international ARM-like programs such as the European Cloudnet project. Furthermore, assisted to the conceptual design of the next-generation radar systems for the US DOE climate research facilities. In the DOE Atmospheric Systems Research (ASR) program I serve as the leader of the ASR radar science group with 50 members (University Professors and research scientists) that is responsible for ensuring the best use of the ARM radar facilities ( My primary role is to represent the ASR science team perspective, recommendations, and priorities; and to communicate directly with the Radar Engineering and Operations Group to ensure the optical utilization of the ARM radar facilities to meet the scientific needs of the users.From 2010 to 2013 I served as the Chair of the American Meteorological Society (AMS) Committee on Radar Meteorology. I have organized and chaired numerous sessions in AMS, AGU and ASR conferences.
TEACHING
Since joining the Department of Atmospheric and Oceanic Sciences (ATOC) at McGill University I have taught six different courses: 2 in the Earth System Science (ESYS) undergraduate program and 4 in ATOC (3 graduate level). I have taught a total of 17 classes at McGill in 13 semesters. My overall rating as instructor for all McGill courses equals the Departmental mean, and is significantly higher for courses in which I am the sole instructor. As a core faculty member of the McGill ESYS undergraduate program from its inception, I have been involved in the development of the ESS curriculum and in the development of 2 of its core courses. In addition, I have worked in the development of an advanced graduate course in atmospheric and oceanic remote sensing (ATOC 626) and an advance graduate course on statistical methods in atmospheric research (ATOC 551). I am presently supervising at McGill 1 Master student, 3 PhD students, 1 research associate, one senior research associate and two postdoctoral fellows. I have graduated 4 Master students and 3 PhD students. I supervise undergraduate students in summer research projects every year. I have also co-supervising 1 Masters and 2 PhD student at the Division of Meteorology and Physical Oceanography at the University of Miami. Since the beginning of my appointment at McGill, I taught the following classes in the context of the Department of Atmospheric and Oceanic Sciences (ATOC) and Earth System Science (ESYS) undergraduate bachelor program. The nature of the ESYS program is to have team teaching in all core courses.
