Graduate Research Topic
My thesis research is focused on quantifying the role that mixotrophic algae play in freshwater pelagic food webs. Mixotrophs, which are algae that combine photosynthetic production with heterotrophic consumption, are currently well identified in the literature, but their effects on both primary production and trophic transfer rate estimations are largely unknown. Utilizing stable isotopic tracers in conjunction with lab and field experimentation, I am developing a framework with which to address these questions for the first time.

  • Undergraduate Institute: Cornell University (Earth Systems)

Personal Statement
Before coming to ESF, I worked in several laboratories at Cornell. The focus of the work was broad in scope, including ichthyology, limnology, stable isotope analysis and microbiology. My graduate work focuses on the catfish of the family Pimelodidae, particularly the giants of the genus Brachyplatystoma, which undertake spawning migrations of thousands of kilometers in the Amazon River. Using microelemental analysis of otoliths, I aim to determine phylogenetic patterns of migration within the family.

Graduate Research Topic
Determining patterns of migration within the Amazonian catfish family, Pimelodidae, using otolith microelemental data.

  • Area of Study: Fish & Wildlife Biology & Management
  • Undergraduate Institute: Western Phillippines Univ (Aquatic Biology)

Personal Statement
I am a Ph. D. student majoring in Fish and Wildlife Biology and Management at SUNY ESF in Syracuse, NY. I also worked with Dr. Donald Stewart’s lab for my MS Degree but before I came to ESF, I was a faculty member of the Aquatic Biology Program of Western Philippines University in Puerto Princesa, Philippines. My MS research focused on taxonomy and conservation of the minnow genus Puntius in northern Palawan, Philippines. Currently, my graduate research in ESF deals with fish community patterns in riverine and coastal ecosystems of Honda Bay Basin. My research aims to compare the species composition of fishes from rivers, estuaries, and coral reef areas in Honda Bay area in Palawan, Philippines. The main goal is to assess the connectivity of these ecosystems in terms of supporting the different life history stages of several commercially important species in Honda Bay. I hope that through the results of my study, sound management programs will be formulated and implemented to effectively delineate marine protected areas that will provide umbrella protection to the different ecosystems that support the Honda Bay area fish communities.

Graduate Research Topic
Riverine and Coastal Fish Community Patterns in Honda Bay, Puerto Princesa City, Philippines
