Dr. Nagler’s research
interests cover the broad area of fish reproductive biology. There are
several avenues of current research emphasis that utilize two different fish
models, the rainbow trout and Japanese medaka. One area is the endocrinology
of estradiol within the fish gonad and the functional implications for sexual
development. An extension of this work is an investigation of the effect of
environmental estrogens on the germ cells of the sexually maturing male
rainbow trout. Another area is an effort to map and model novel and known
genes from the pituitary-gonad axis that control the photoperiod- induced
annual reproductive cycle of the female rainbow trout. Several projects are
examining factors that lead to fertility problems in female rainbow trout
used as brood stock for aquaculture. There is a project employing a
microarray approach to identify novel genes that are associated with female-
and male-specific patterns of early molecular differentiation in the rainbow
trout gonad. Lastly, Dr. Nagler leads a team that is designing a device using
nanoscale materials for the electrical detection of DNA sequences for genomic
screening. He teaches an upper-division undergraduate course on Ichthyology,
a graduate course on Reproductive Biology of Fishes, and participates in a
team-taught course on applications of nanoscience for biomedicine.
