Dr. Ting-Feng Lin received his BS in Sports Medicine from China Medical University in 2010. He obtained his MS in Physiology from the National Taiwan University in 2014, working in the neurophysiology lab of Dr. Chih-Yung Tang, where he studied the biophysical properties of voltage-gated potassium channels (Eag and Erg) and their associated proteins by applying both molecular and electrophysiological techniques. He earned his PhD in Neuroscience from the University of Zurich in 2019, where he worked in the vestibulo-oculomotor lab of Dr. Melody Ying-Yu Huang. During his thesis work, he investigated oculomotor behaviors in zebrafish. Specifically, he discovered and characterized the negative optokinetic afternystagmus caused by an inherent bias of the OKN gain. The negative optokinetic afternystagmus is a result of the set-point adaptation of the retinal slip velocity, which takes place during both growth and aging and is crucial for animals to perform precise visual motor tasks. During his postdoctoral training, he moved to the Neurobiology of Learning and Memory lab of Dr. Christian Hansel at the University of Chicago, where he used in vivo two-photon imaging to identify the distinctive functions of synaptic long-term potentiation (LTP) and non-synaptic intrinsic potentiation in Purkinje cells of the mouse cerebellum.

Dr. Melody Ying-Yu Huang received her BS in Biochemical Science and Technology (formerly Agricultural Chemistry) from the National Taiwan University in 1999. She obtained her MS in Biotechnology from the University of Pennsylvania in 2002, working in the cancer genetics lab of Michael Pack, where she used forward genetics approaches and conducted genetic mapping of the zebrafish slim jim (slj) mutants. She earned her PhD in biology from the Swiss Federal Institute of Technology (ETH) in 2007, where she worked in the vision research lab of Stephan Neuhauss. During her thesis work, she applied genetic and behavioral visual function analyses to the early development of the zebrafish nervous system. She discovered that zebrafish belladonna (bel) mutants, which first drew attention owing to retinotectal misprojections and reversed optokinetic response, exhibit peculiar spontaneous eye oscillations that closely resemble a rare human congenital ocular motor disorder: infantile nystagmus syndrome (INS). During her postdoctoral training and later as an independent PI, she moved to the Neurology Clinic at the University Hospital Zurich, which hosted her to establish the zebrafish INS model for bench-to-bedside translational research. Nystagmus research, being essentially in a deadlock due to the unavailability of a suitable animal model, has been greatly leveraged through her critical discovery of the zebrafish INS model. Exploiting this model, she and her team conducted many research projects that garnered attention from the international scientific community in the field of research. Since 2019, Dr. Huang has been the head of the lab and group leader at the University Clinic for Anesthesiology and Pain Therapy and the Department for BioMedical Research of the University of Bern.

Collection Overview

Zebrafish are among the simplest and smallest vertebrates used as model organisms in laboratories. The use of the zebrafish model (Danio rerio) in research is rapidly expanding due to various advantages. Zebrafish are inexpensive, easy to maintain, and highly fecund. It is possible to obtain a complete genome sequence and well-established mutants. Due to the size and transparency of zebrafish larvae, image acquisition may be the most popular experimental approach in zebrafish models. With these advantages, scientists can see through the body of a zebrafish and directly observe the organism's machinery.

However, experimental preparations can also be complex due to underwater procedures, miniature body structures, and difficult-to-handle shapes. Therefore, to obtain data with quality and efficiency via image acquisition, scientists need selective labeling (e.g., a cell type-specific fluorescent label), a practical toolkit at the bench, and a goal-directed analysis. Within the relatively small and young scientific community, established methods in individual laboratories are either unavailable to others or awaiting further development.

This Methods Collection aims to investigate and share novel zebrafish imaging methodologies as well as improvements to previously established methods for answering scientific questions through image acquisition. The scope includes sample preparation, marker labeling, equipment setup, and image analysis.
