In real life, my name is Han-Kwang Nienhuys. I have a background in physics and chemical physics, more specifically time-resolved spectroscopy and lasers.

I know a few things about Netherlands and Sweden. Since 2009, I can add photolithography for the semiconductor industry to that, or at least a tiny bit of a particular aspect of it. Although I do not have a formal medical background, I think I'm fairly skilled in spotting pseudoscientific nonsense that is touted by commercial websites and subsequently finds its way into health-related Wikipedia articles.

Contributions
This section is horribly incomplete and out-of-date.

Pet articles: Furthermore, I try to keep an eye on linkspam and evident (scientific) nonsense.
 * Template:nutritionalvalue - I'm slowly adding nutritional data to food-related articles.
 * Winemaking
 * Laser-related: Chirped pulse amplification, prism compressor, EN 207, Femtosecond pulse shaping, Terahertz time-domain spectroscopy, Laser safety
 * Optics-related: Triangular prism (optics)
 * Physics: Poynting vector
 * Misc: Potato cyst nematode
 * Transfer-matrix method (optics)

Older contributions
For historical reasons some of the articles I contributed to in a time (2004) when it was very easy to add relevant new content to stubs and missing articles:
 * Lasers: Laser,  List of lasers,  Nd-YAG laser, Ti-sapphire laser,  dye laser, Laser safety
 * Spectroscopy: Absorbance,  Electromagnetic spectroscopy, Electron spin resonance,  Molar absorptivity,  Nuclear magnetic resonance,  Spectroscopy, Spectrophotometry,  Time-resolved spectroscopy,  Transmittance
 * Physics: Nonlinear optics,  Speed of light
 * Chemistry: Recrystallization,  Supersaturation
 * Mathematics: Eigenfunction,  Orthogonal functions,  Kramers-Kronig relations
 * Sweden: Allemansrätten,   Lund,  Image:Lunds domkyrka.jpg
 * Netherlands: Gouda cheese
 * Color vision: Color,  Gamma correction,  Gamut, International Commission on Illumination,  Image:Gamut.tar.gz,  Image:Cie chromaticity diagram wavelength.png
 * Miscellaneous science/technology: Binaural recording, Microphone,  Microwave oven,  Microwaving
