Aubrey Gorbman Endowed Lecture: Multimodal communication and reproductive-dependent sensory plasticity in an African cichlid fish

Animals live in a multisensory world and use different sensory channels to communicate during crucial behavioral contexts such as aggression and reproduction. Despite the importance of this multimodal communication, there are relatively few species in which information on sender signals and receiver responses are known. How do individuals send information in multiple sensory channels and where is this information processed and integrated in the receiver’s brain to produce context-dependent behaviors?

Building an integrated framework for tissue morphogenesis with the zebrafish inner ear

How simple tissues give rise to geometrically complex organs with robust shapes and functions is a fundamental question in biology with important implications in disease and translational medicine. The current mechanistic framework explains how upstream genetic and biochemical information pattern cellular mechanics and thereby tissue dynamics. In this framework, the main driving force is cell-intrinsic and generated by actomyosin contractility.

Unwrapping Glial Engineering in the Vertebrate Nervous System

The long-term goal of the Kucenas Lab is to fundamentally understand the cellular and molecular mechanisms that mediate neural-glial and glial-glial interactions during nervous system development and injury/regeneration. Using Danio rerio (zebrafish) as a model system, we combine genetic and pharmacological perturbation, single cell manipulation, laser ablation/axotomy, small molecule screening, and in vivo, time-lapse imaging to directly and continuously observe glial cell origins, behaviors, and interactions in an intact vertebrate.
