October 29, 2025, Filed Under: NewsFall 2025 Hans is quoted in an article in The Scientist on The Complex Lives of Cichlid Fish Parents. Emily has accepted a 3 year Fundação para a Ciência e a Tecnologia postdoctoral fellowship to work in Rui Oliveira’s Integrative Behavioral Biology Lab at the Gulbenkian Institute for Molecular Medicine in Lisbon (Portugal). This is an amazing opportunity to work with some of the best social neuroscientists, and in a beautiful city (and near the ocean!) to boot! Congratulations, very well done! We are welcoming Demetrius Phofolos as a new graduate student to our lab! Demetrius joins the Ecology, Evolution & Behavior Graduate Program after having worked as an Inland Fisheries Researcher for the New Hampshire Fish & Game Department for the past couple of years.
October 29, 2025, Filed Under: NewsSummer 2025 Listen to Hans’ presentation in this Society for Neuroscience Webinar on Neurogenomic Adaptations to Variable Environments. Hans was interviewed by The Cichlid Stage Blog, “the most comprehensive cichlid blog on the Web!” Check it out! Great news! Isaac has been awarded the 2025 WC Young Recent Graduate Award of the Society for Behavioral Neuroendocrinology! Congrats, Isaac, on this well deserved recognition! Congratulations to Sarah, who has received the Edward C. Raney Fund Award from the American Society of Ichthyologists and Herpetologists (ASIH) for her project on the Neural Basis of Shoaling Behavior in a Cichlid Fish!
October 29, 2025, Filed Under: NewsSpring 2025 Listen to Hans’ presentation at the Kavli foundation and Allen Institute Symposium on Neurobiology in Changing Environments. Congratulations to Sarah Muh, who has received an Honorable Mention on her NSF GRFP application! This is a great achievement, especially considering that NSF only awarded about half as many fellowships this year compared to prior years. Very cool news: Emily has been selected to present her research at the first installment of the all new 2025-2026 Future of Neuroethology Webinar series by the International Society for Neuroethology! She is one of only three trainees that have been given this opportunity! The webinar will take place on May 20th at 11am, mark your calendars! Congratulations to Jennie and Sarah, who have both been awarded IB Research or Travel Grants in support of their research! Sarah received $2500 from the Hamilton Endowed Graduate Fellowship to study the Neural basis of Shoaling Behavior in a Cichlid Fish. And Jennie received $2500 from the Blair Scholarship Fund in Zoology to examine the Neural Mechanisms of Bumblebee Construction Behavior. Amazing news: Landon has been awarded the Evolutionary, Ecological, or Conservation Genomics (EECG) Research Award by The American Genetic Association for his project ’Disentangling the Function of the V1a2 Vasopressin Receptor as a Regulator of Social Dominance Behavior in a Highly Social Cichlid Fish’. Wonderful news: Emily has been selected as a finalist for the CNS Visualizing Science competition for the whole mount isHCR images she submitted! This award comes with a $250 check, which is a nice bonus! Congratulations to undergraduates Camille Brown, Abby Beman, and Anouka Saha! Camille will be joining Andres Bedensky’s lab at Columbia University for her doctoral studies! Abby has committed to the Quantitative and Computational BioSciences PhD program at Baylor College of Medicine after getting offers from all five schools she applied to! She’ll be pursuing her interests in the analysis of genomics data in the context of human genetic diseases. And Anouka has accepted an offer to the EEB graduate program at Washington University in St Louis! She will likely join Andi Kautt’s lab but has plans to also rotate with Jonathan Losos and Michael Landis in her first year.
