David Ferguson

David Ferguson

Langmuir
Post-Doctoral Fellow

David is an igneous geochemist and volcanologist who uses the chemistry of lavas to understand different process in magmatic systems. He is currently a member of Charles Langmuir’s research group, working on links between volcanism and glacial cycles in volcanic arcs.

He completed his MSc at University College London and PhD at the University of Oxford, where he worked on magmatism associated with continental rifting in Ethiopia. Before joining the Langmuir group David was a Postdoctoral Fellow at the Lamont-Doherty Earth Observatory, Columbia University, New York.  He is broadly interested in exploring links between magmatic activity and other tectonic and climatic processes. Previous and ongoing projects include work on volcanic activity in Ethiopia, Chile and Hawaii. David’s research at Harvard is focused on geochemical and geochronological studies of volcanism in the Cascades, which involves collaborative work with scientists from the U.S Geological Survey.  

Maya Gomes

Maya Gomes

Johnston
Visiting NASA NAI Post-Doctoral Fellow

Maya is interested in how the cycling of elements through the ocean and atmosphere regulates climate and habitability. Specifically, she focuses on how the sulfur cycle interacts with the carbon, oxygen, and nutrient element cycles. She compares patterns of biogeochemical cycling in time periods when marine sulfate levels were low, like they were on the early Earth, to periods when marine sulfate levels were high, like they are in the modern ocean.

Yuandu Hu

Yuandu Hu

Post-Doctoral Fellow
Perez-Mercader Lab, Rowland Institute

Yuandu Hu studied in Huazhong University of Science and Technology in Wuhan China and earned his PhD in June 2013, majoring in Polymer Chemistry and Physics. He focused mainly on the fabrication of functional soft materials (e.g. shape controllable microgels and stimulus-responsive photonic crystal microparticles) by combining microfluidic techniques and self-assembly of colloidal particles together.  Prior to joining the Perez-Mercader group in September 2014, he spent one year in the University of Notre Dame in Indiana as a postdoctoral research associate. His work at Notre Dame dealt mainly with the fabrication of Janus microgel particles and self-propelling materials to mimic mircoorganisms' motion behavior.i

 Research Interests: Origin of Life, Microfluidic Technology, Hydrogel Based Soft Materials, Self-assembly of Colloid Particles, Interface Phenomenon, Chemomehanical System, Unilamellar Vesicles, and Self-Oscillation System Driven by B-Z Reaction.

Nagissa Mahmoudi

Nagissa Mahmoudi

Pearson
Post-Doctoral Fellow

Nagissa is broadly interested in microbial degradation of organic compounds including anthropogenic pollutants as well as natural organic matter. Nagissa completed her  B.Sc. in Integrative Biology from the University of Toronto in Canada. Subsequently, she earned her PhD at McMaster University in Canada where she employed a variety of tools, ranging from isotope geochemistry to high throughput sequencing, to investigate microbial communities in petroleum impacted environments. This research involved assessing microbial carbon sources using natural abundance radiocarbon analysis of lipid biomarkers and subsequently linking degradation to specific taxonomic groups. 

Prior to joining Ann Pearson's research group, Nagissa was a post-doctoral fellow at the University of Tenensee Knoxville where she investigated the biodegradation potential of native microbial communities in deep sea basins. Nagissa was awarded an NSERC Post-Doctoral Fellowship to work at Harvard to investigate factors that constrain microbial carbon cycling in marine sediments.

Alan Rooney

Alan Rooney

Macdonald
Visiting Post-Doctoral Fellow

Alan’s research principally focuses on gaining an understanding of the interactions between tectonic, geochemical and climatic processes on a range of time scales. To better understand these interactions, he employs isotope geochemistry; in particular, the rhenium-osmium (Re-Os) geochronometer and Os and Sr isotopes. Alan’s research interests are spread across three main categories; 1) Proterozoic Earth history with particular attention on the nature of Neoproterozoic (1000 – 541 Ma) glaciation, large-scale tectonic reorganizations and eukaryotic diversification; 2) combining geochemical proxies with microfossil and sedimentological analyses from modern-day glaciated regions to better understand climatic variations and the external and internal forces acting on ocean-ice sheet dynamics throughout the Quaternary; and 3) improving our understanding of hydrocarbon systems through the use of Re-Os geochronology and Os isotopes to aid oil-to-source rock correlations.

Fatemeh Sedaghatpour

Jacobsen
Post-doctoral Fellow

Fatemeh Sedaghatpour has received her PhD in Space and Planetary Sciences from Arkansas Center for Space and Planetary Sciences at the University of Arkansas in 2013. She has joined Professor Stein Jacobsen’s group as a postdoctoral fellow in Jun 2013. Her research involves stable isotope cosmochemistry to study the early solar system, origin and evolution of planetary bodies. Her current research is focused on Mg and Ca stable isotope systems in lunar samples and meteorites samples using high precision isotopic analyses to have a better understanding of the Moon’s origin and evolution, and investigate the planetary formation processes.

Martin Singh

Kuang
Post-Doctoral Fellow

My research focuses on the circulation of the atmosphere on a range of spatial scales. In particular, I am interested in the role of moist processes in determining the character of atmospheric circulations, both on the scale of clouds and the planetary scale, and how these circulations may change in a warmer world. Currently I am a postdoctoral fellow working with Zhiming Kuang on the dynamics of monsoons.

My work primarily involves using atmospheric models in idealized geometries to understand the fundamental processes that act to influence the dynamics of the atmosphere. But I also use observations and models in more realistic configurations to connect the model world to the real world.

I received my PhD in 2014 from the Massachusetts Institute of Technology where I worked on understanding the behavior of moist convection at different surface temperatures using simulations of radiative-convective equilibrium and observations of the tropical atmosphere.
