I don't have real-time data access, but I can guide you on how to find a dermatologist at the WEA Clinic in Chennai. Here's what you can do:

1. **Clinic's Official Website**: Check if the WEA Clinic has an official website. They often list their doctors, including dermatologists, along with their qualifications and contact details.

2. **Online Medical Directories**: Websites like Practo, Justdial, or Sulekha can help you find dermatologists at specific clinics. You can search for "WEA Clinic dermatologist Chennai" on these platforms.

3. **Contact the Clinic Directly**: You can call the clinic directly and inquire about their dermatologists. They can provide information on appointment availability and the specific doctors working there.

4. **Social Media and Reviews**: Sometimes, clinics have social media profiles where they post updates and information about their doctors. Reviews on platforms like Google Reviews can also offer insights into the clinic and its practitioners.
