Congrats Dr. Buck!

Congratulations to Cara Buck who obtained her PhD today. She was given the challenge of setting up a brand new technique in the lab (ultrasonic vocalization recordings) and an even bigger challenge in making sense of what they mean.

Lots of hard work, long days and endless recordings later, she not only setup the technique but managed to published 3 papers with one more in submission.

Her work unveil some of the neurobiological mechanisms underlying ultrasonic vocalizations, and clearly demonstrate that different types of vocalizations are tightly associated and sometimes even predict the motivation for food and alcohol in animals that have been deprived.

Great job Cara, well deserved Dr. Buck!

If you are interestd in ultrasonic vocalization and motivation/addiction, below are the papers.
