My research focuses on developing new tools and constraints to evaluate mathematical models of physical processes and Earth structures. I am currently working to develop new theoretical and observational frameworks to utilize the information about earthquake source processes and Earth structure contained within long-period recordings of seismic energy.

Felix is a microbial biogeochemist studying the lipid "fingerprints" of archaea and bacteria ‒ microorganisms that control the cycling of elements such as carbon and nitrogen on our planet. His research focuses on reconciling microbiological lab experiments with geochemical observations from the modern ocean to improve the application of microbial lipids for the reconstruction of past environments.He received a B. Sc. (2009), M. Sc. (2012), and PhD (2015) from the University of Bremen, Germany. Felix joined Prof. Ann Pearson’s lab in January 2016, where he investigates the use of stable isotopes of archaeal lipids as tracers for changes in the oceanic carbon cycle in the past and modern ocean.
I am a seismologist interested in ambient seismic sources and the way they illuminate the subsurface to provide us nearly continuous information about Earth structure. I am utilizing ambient noise to study the site response of sedimentary basins, which is an important hazard factor during earthquakes. It may also reveal how sedimentary basins, which underlie many towns and cities, respond to environmental changes.
I’m interested in connections between the geologic and biospheric carbon cycles. Specifically, my work aims to understand how processes occurring in river basins transfer carbon between these two cycles in order to regulate atmospheric CO2 concentrations over geologic timescales. To do so, I combine a suite of isotope geochemistry techniques (including compound-specific isotope measurements and novel reaction monitoring methods) with inverse models, satellite products, and geospatial analysis. My current projects include analysis of multi-year time-series samples from the Ganges-Brahmaputra and Congo Rivers, high-frequency samples from mountainous rivers in Taiwan, isotope analysis of bacteriohopanepolyols in continental shelf sediments, and development of the Ramped PyrOx radiocarbon instrument. I'm additionally working on reconstructing the mechanisms that control Cenozoic CO2 variability using inverse modeling methods.Read more
I work jointly between Harvard and the Lamont-Doherty Earth Observatory at Columbia University in the field of observational geodynamics. My research encompasses problems related to the structure, deformation, and flow of Earth's mantle. Geological processes include mantle convection, glacial isostatic adjustment, and lithospheric deformation, and I use tools including seismology, landscape evolution, geochemistry, sediment stratigraphy, and the elevation of sea-level markers. Recently, my work has been focusing on building models of 3D Earth structure for sea-level modelling and investigating the genesis of sediment-hosted metal deposits in sedimentary basins surrounding thick lithosphere.

Post-Doctoral Associate 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.
My research focuses on advancing our understanding of Earth structure through seismic imaging using both ambient noise and earthquake data. With high-accuracy tomography models at both continental and local scales, my research is motivated by questions about tectonic processes at various tectonic settings, including sedimentary basins, fault zones, magmatic systems, and orogens. My other research interest includes using seismic interferometry to monitor subtle changes in basin aquifers and volcanos on societally relevant time scales.
Post-Doctoral Fellow Perez-Mercader Lab, Rowland Institute
Dr. Samuel Pearce is a Post-doctoral Fellow in the Perez-Mercader group. He earned his Ph.D. at the University of Bristol, UK in February 2019 under the supervision of Professor Ian Manners. His graduate studies focused on the synthesis of uniform 1D and 2D block copolymer nanostructures using solution-based self-assembly protocols. He then moved to Harvard University in November 2019. Samuel’s research interests broadly encompass innovative synthetic approaches involving materials chemistry and self-assembly, with a view for their application in fields such as nanoscience and origins of life research. His current research focuses on the development of adaptive polymerization-induced self-assembly systems, with the aim to construct artificial cell-like structures capable of responding spontaneously to changes in their environment.Read more
Post-Doctoral Fellow Knoll - Pierce - Lauder Groups Junior Fellow of the Society of Fellows
Elizabeth is both a paleontologist and biological oceanographer. She is broadly interested in the evolution, structure, and function of ocean ecosystems. She uses a multi-proxy approach to study how the open ocean ecosystem has changed through time, with a focus on how it has responded to climate and biotic events in the past. Elizabeth works primarily with ichthyoliths, microfossil fish teeth and shark scales found in deep-sea sediments world wide, which preserve an unparalleled record of fish diversity, abundance, and community structure through geologic time.
Giuseppe Torri is interested in Atmospheric and Climate Dynamics. His research focuses primarily on deep convection using the combination of Large Eddy Simulations/Cloud Resolving Models and a Lagrangian Particle Dispersion Model to obtain a process-level understanding of the fundamental dynamics of such systems. Currently, he is working on applying the techniques he developed so far to the study of supercell storms, with the hope of improving forecasting skills. He is also interested in topics related to the interaction between the land surface and the atmosphere, aiming to answer important questions about long-term impacts of land use on climate at the regional and global scale.
Originally from Germany, I finished my doctorate at the Ludwig Maximilians University in Munich in 2016. I am interested in how magnetic fields evolve with time, especially in the early solar system during planet formation. So far, my research is focused on the fundamentals of remanence acquisition and can be broadly divided into three main themes. (1) the magnetic properties of materials associated with meteorites, (2) the effect of high pressure on magnetic properties of minerals and (3) the rock magnetism of ultra-fine particles. By understanding these fundamental recording processes, we will be able to have a more robust interpretation of the magnetic signals that are retained in meteorites. At Harvard, I will be able to combine my interests and work on the fascinating and complicated paleomagnetic record of Mars.Read more
I study theoretical aspects of atmospheric dynamics. My research aims to improve our understanding of the wide variety of scales in the atmosphere to bridge the weather-climate gap, especially the role of moist convection on high-impact extreme weather and climate events.
I have recently obtained a Ph.D. from The University of Chicago. My dissertation research is focused on the fundamental dynamics of a 20-30 day periodic behavior in the storm tracks – a newly identified climatic driver and early warning of extremes. Read more
