  • “Deep-time” paleoclimatology (specifically Cenozoic Era)
  • Organic geochemistry paleothermometry
  • Paleoceanography
  • Stable isotope geochemistry
My research interest is broadly centered around deep-time paleoclimatology (prior to ~2.6 million years ago). To understand how our Earth’s climate operates in the warmer conditions, I am interested in using organic biomarker-based paleothermometer (e.g., TEX86 and UK’37) to reconstruct an extended reliable history of the ancient earth’s sea surface temperature for the entire Cenozoic Era.

Development Petroleum Geologist | Chevron Thailand Exploration And Production, June 2013 – June 2018

  • Identify hydrocarbon potentials and conduct detailed geological assessments within the extensional basin (mainly fluvio-deltaic depositional environments) based only multiple data sets including wireline logs, 3D seismic profile, and historical production data
  • Manipulate geological data from over 5,000 drilled wells and establish meaningful data visualizations: detailed pore pressure analysis and geo-statistical reserves booking
  • Integrate cross-disciplinary data including geological, petroleum engineering, and drilling engineering data to optimize hydrocarbon exploration and production
  • Re-evaluate and discriminate regional pore pressure and temperature regime to enhance the accuracy of predrilled reserves prediction for all undeveloped projects in the Gulf of Thailand
  • Developed a new method for reservoir pressure evaluation using wireline logging and gas show

Chief Scientist: Dr. Jessica Fitzsimmons

Co-Chief Scientist: Garrett Walsh

  • Collected seawater samples with Niskin bottles in Galveston bay


Shore-based Operational Geologist | Chevron Thailand Headquarter, Bangkok, Thailand

  • Project(s) Duration: 6 months, July – December 2017
  • 2 infill projects in Jakrawan Gas Field: 20 wells drilled with 90% accuracy between pre-drill and post-drill hydrocarbon reserves estimations
  • Conducted real-time stratigraphic correlation (wireline triple combo) and re-evaluated pore pressure profile during drilling operations
  • Evaluated economic justifications on a well-by-well basis to optimize project costs and maximize hydrocarbon resources


Wellsite Geologist Trainee | T-11 Tender Rig, Gulf of Thailand, November 2nd – 13th, 2014

  • Observed and learned real-time drilling operations at Moragot E platform, Moragot gas field, the Gulf of Thailand
  • Learning activities: Formation pressure acquisition (HSFT-II tool), Formation Integrity Test (FIT), Rig-floor operations


Beside research, I am a Thai Fulbright scholar and an ultra-trail runner. With that being said, I like to spend my time in nature, up and down mountains. Also, I am always keen to learn all cultural experience and share some Thai believe and culture along my academic journey in the United States.
