Philip Hertzler

Philip Hertzler is an Associate Professor in the Department of Biology at California State University, Long Beach, within the College of Science & Engineering. His research and teaching are centered on developmental biology and aquaculture, particularly in marine shrimp species such as Sicyonia ingentis, Litopenaeus vannamei, and Marsupenaeus japonicus.

Education:

• B.S., Goshen College, 1985
• Ph.D., University of California – Davis, 1993
• Postdoctoral Training, Duke University, 1993–1998

Dr. Hertzler's research focuses on embryonic development in crustaceans, with emphasis on germ line specification, muscle development, and early cell lineage. His lab employs molecular biology, microscopy, and embryo manipulation techniques to study gene expression (e.g., vasa, nanos, pumilio) and RNA-positive granules in germ line formation. His work provides foundational insights into invertebrate developmental mechanisms and has applications in aquaculture.

The recent publications reflect a strong trend in developmental genetics and comparative embryology of marine invertebrates, particularly decapod crustaceans. His work integrates cell biology, genomics, and evolutionary developmental biology, contributing to broader understanding of mesoderm formation, gastrulation, and germ cell development across species.

Scientific Awards:

Dr. Hertzler has successfully secured research funding from CSIRO, Australia, supporting his investigations into shrimp development. He actively mentors graduate students, several of whom are co-authors on his publications, indicating a strong advising role. His lab serves as a training ground for students in developmental biology and molecular techniques.

His research is conducted through a dedicated laboratory focusing on marine shrimp embryogenesis, where his team investigates germ granules, cell lineage, and muscle development using advanced imaging and molecular tools.
