Study Program and Research

 

In May 2010, I received my doctoral degree from Harvard University - School of Public Health, Boston, MA, U.S.A.

Degree Title: Doctor of Science (Sc.D.) in Environmental Health
Concentration: Occupational Health
Coursework Emphasis: 1)  Industrial Hygiene
2)  Ergonomics and Safety
Research Topic: Novel Exposure Assessment and Early Neurotoxic Effects of Manganese in Exposed Workers
Advisor: Marc Weisskopf, M.S., Ph.D., Sc.D.
Mark and Catherine Winkler Professor of Environmental and Occupational Health
Specific Studies:  
  • Study #1 - Assessment of Occupational Exposure to Manganese and Other Metals in Welding Fumes by Portable
    X-ray Fluorescence Spectrometer
    Laohaudomchok, W; Cavallari, JM; Fang, SC; Lin, X; Herrick, RF; Christiani, DC; Weisskopf, MG
    This study aimed to determine whether the portable X-ray Fluorescence (XRF) spectrometer is suitable for analysis of metals (Mn, Cu, Cr, Fe, and Zn) in welding fume samples collected on 37mm air filters. 

  • Study #2 - Toenail, Blood, and Urine as Biomarkers of Occupational Exposure to Manganese
    Laohaudomchok, W; Lin, X; Herrick, RF; Fang, S; Cavallari, JM; Christiani, DC; Weisskopf, MG
    This study aimed to examine the correlation of several biomarkers (toenail, blood, and urine) and work history (as measured by Cumulative Exposure Index; CEI), and correlations of these biomarkers. 

  • Study #3 - Neuropsycholological Effects of Low-Level Manganese Exposure in Welders
    Laohaudomchok, W; Lin, X; Herrick, RF; Fang, S; Cavallari, JM; Shrairman, R; Landau, A; Christiani, DC; Weisskopf, MG
    This study aimed to examine the association between work history (as measured by CEI) and neuropsychological test scores, and association between exposure over a work shift and performance on these tests. 

  • Study #4 - Psychiatric Effects of Low-Level Manganese Exposure in Community-dwelling Men
    Laohaudomchok, W; Diao, N; Weisskopf, MG
    This study aimed to examine the association between cumulative non-occupational exposure to manganese (as measured by Mn in toenails) and psychiatric symptoms reported using the Brief Symptom Inventory (BSI).
