Using emerging technology, natural history collections, field research, and genetics to describe marine mammal diversity for conservation management decisions. I also strive to inspire others to fall in love with Earth's wildlife and wild places through teaching and public education. Currently, I am a Secretary's Distinguished Research Fellow at the Smithsonian Institution's National Museum of Natural history. In this position, I am investigating the evolutionary relationships of balaenopterid whales using skulls, DNA, and drones.

September 2017: Earlier this month, I was awarded the Secretary's Distinguished Research Fellowship to continue my investigations of the balaenopterid family tree. I'm excited for the opportunity to uncover more secrets of whale evolution with this prestigious opportunity.

"One of the hallmarks of the Smithsonian Institution’s James Smithson Postdoctoral Fellowship is the opportunity to gain an understanding of the interplay between scholarship and public policy. In May 2017, Dr. Matthew S. Leslie – the Secretary G. Wayne Clough Fellow (awarded through the James Smithson Fellowship Program) at the Smithsonian’s National Museum of Natural History (NMNH) & National Zoological Park (NZP) – was invited to do just that on an international scale."

Published in Frontiers of Marine Science: Leslie & Morin - Using Genome-Wide SNPS to Detect Structure in ETP Dolphins!!
Millions of dolphins were killed in the eastern Pacific tuna fishery. This is why we have "dolphin-safe" tuna now. Thankfully, now only a relatively small number of dolphins are killed. But despite this, the dolphin numbers remain low - they haven't shown signs of recovery. In this study, I used large scale DNA data to solve a sticky question of how many breeding groups (i.e., populations) of dolphins were/are affected by this fishery. This is important because even the lower kill rate could impact recovery if it was concentrated on a small local population. For one of the species I studied, my data showed four populations: three that were known and one that was suspected. This means we were managing three of the four populations correctly. The one we weren't getting right is a small local population that needs special protection.
Knowing how many populations live in this area had been a tough problem to answer. Its been fun to apply new techniques to old specimens to answer it.
Smithsonian's 2016 Smithson postdocs attend Student Conference on Conservation Science - October 20th-22nd 2016 - American Museum of Natural History. THis meeting is organized by the AMNH Center for biodiversity conservation to provide "opportunities for emerging scientists to professionally network, gain experience, and present and get feedback on their work. Interactions with peers as well as leaders in science, policy and management will encourage collaborations, inspire further research, and create lasting professional connections."
A large group of researchers from the National Museum of Natural History attended the Senate Briefing on Marine Mammal Bycatch on September 14th, 2016. Pictured here is much of the group with several members of the U.S. Marine Mammal Commission and Dr. Andy Read (Duke University) an honorary panelist. From left to right: Dr. Matt Leslie, Dr. Chris Marshall, Dr. Aly Fleming, Dr. Daryl Boness, Dr. Frances Gulland, Dr. Peter Thomas, Dr. Andrew Read, Dr. Nick Pyenson and Charley Potter
September 7th 2016 was a good day. I couldn't be more excited to work for such an amazing institution!
These short videos illustrate some of what I do. Enjoy!
