Dr. Sessa’s research focuses on the evolution of shallow marine ecosystems through time. She employs the fossil record as a natural laboratory through which to study how organisms responded to environmental perturbations. Mollusks are the primary focus of her research because they are well preserved and abundant in fossil and modern assemblages. Additionally, the chemistry of mollusk shells records seasonal temperature variations, which she uses to reconstruct past climates. Jocelyn has tracked the response of marine organisms to the Cretaceous-Paleogene mass extinction and to climatic fluctuations, including the Paleocene-Eocene Thermal Maximum. The latter is one of the best geological examples of a rapid global warming event. She has recently begun working to reveal the diversity and community structure of mollusk assemblages from the ancient tropics of southern Africa. Prior to joining the American Museum of Natural History, Jocelyn was a Post-Doc Fellow with the Department of Paleobiology of the Smithsonian National Museum of Natural History.

What were ammonites' lives like? Isotope study reveals clues.
Using isotopic analysis, researchers have revealed new ecological data about ancient mollusks.
By Joseph Dussault, Staff Writer
In medieval Europe, ammonite stones were believed to have divine powers. In Nepal, Hindus have long interpreted them as manifestations of Vishnu.
To Jocelyn Sessa, they’re a window to the past.
At Mississippi’s Owl Creek Formation, researchers are using isotopic analysis to reconstruct the habitats of these ancient mollusks. Armed with new data, they hope to piece together details about prehistoric climates. Their study, which was published Monday in PNAS, was led by Dr. Sessa, a paleontological fellow at the American Museum of Natural History.
Ammonites were a group of marine mollusks, closely related to the octopus and squid of today. They first appeared in the Devonian period, more than 400 million years ago, and group persisted until the Cretaceous-Paleogene extinction event that ended the Mesozoic period. Thanks to their sturdy calcium composition, ammonites' distinctive shells, most of which were simple spirals, tend to be well-preserved and quite common.
And because of their ubiquity, ammonites are considered excellent index fossils. Geologists and paleontologists alike use them as reference points when dating rock layers. But while the “when” is abundantly clear, relative little is known about “how” these mollusks lived.

On Friday, February 5th, Geosciences hosts a talk by Kimberly Ennico-Smith, NASA Deputy Project Scientist for the New Horizons Mission (fly-by Pluto and its moons), entitled "New Views of the Pluto System -- Far From Being Boring, Cold, Dead Worlds." The talk begins at noon in 541 Deike.

Ph.D., Astronomy, Institute of Astronomy, Cambridge University, England
B.A., Physics, Johns Hopkins University
In her capacity as the New Horizons Mission's Deputy Project Scientist, Dr. Ennico-Smith leads the calibration activities and compositional mapping of Pluto and its moon Charon with color imagery and spectroscopy. Among a number of research activities, she is also a Principal Investigator developing innovative telescope designs using small satellites and actively working to mature low-cost, quick turn-around suborbital and balloon payloads that deliver focused science measurements and promote broader hands-on experiences.
Meet Three Scientists Behind the Pluto Mission
By Megan Hickey, PBS Broadcasting, July 24, 2015
Shortly after the July 14 fly-by of Pluto and its moons, we spoke with three members of the New Horizons mission team: Alice Bowman, the mission operations manager, and Cathy Olkin and Kimberly Ennico-Smith, deputy project scientists...about working on a deep space mission, their reaction to the first round of Pluto images, and how to pronounce the name for Pluto’s largest moon, Charon.
Colloquium Speaker Laura Wallace, Research Scientist, Institute for Geophysics, University of Texas at Austin, and 2016 GeoPRISMS Distinguished Lecturer, presents "Sticky or Slippery? Controls on Subduction Megathrust Behavior at the Hikurangi Subduction, New Zealand" at 4 PM in 022 Deike. A pre-talk Coffee & Cookies Speaker Reception takes place at 3:45 PM in the EMS Museum on the ground floor of Deike. All are welcome.
Because the GeoPRISMS Distinguished Lectureship Program is sponsoring Dr. Wallace's participation in our Colloquium, we are looking for good turn-out by the department. GeoPRISMS is an NSF-funded program that supports interdisciplinary and shoreline crossing activities that combine marine and terrestrial approach to study the margins evolution and their dynamics. GeoPRISMS' Distinguished Lecturer is an honor reflecting the quality and impact of the research done by the person selected.
Research Interests, Activities, and Awards
Laura Wallace studies various aspects of tectonic plate movement and subduction zones in New Zealand, including slow slips. She is a specialist in the use of global positioning systems data in this kind of work.
Prior to joining the University of Texas, Dr. Wallace spent ten years working as a geophysicist at GNS Science in New Zealand, one of the best places in the world to study plate tectonics. Much of her scientific career has focused on investigating plate boundary processes at the Hikurangi subduction zone beneath New Zealand's eastern North Island. In 2015/2016 she led the Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS) project. HOBITSS is an international project that uses seafloor instruments to detect deformation of the seafloor during large slow slip events.
Global Positioning System (GPS) data is one of the main types of data used by Dr. Wallace in her research. The GPS data collected at permanent survey marks around New Zealand (and elsewhere in the western Pacific) track the movement of the Earth’s crust at tectonic plate boundaries. Her work using GPS data to track crustal movements has produced new insights into where large subduction “megathrust” earthquakes are most likely to occur on the Hikurangi subduction plate boundary beneath the North Island.
Dr. Wallace discovered the first slow slip event recorded on New Zealand’s GPS network, near Gisborne, in October of 2002. She hopes her research will further the understanding of the relationship between slow slips and earthquakes and tsunamis that have occurred off Gisborne in the past.
