Translational Phototherapeutics Laboratory
Welcome to our laboratory
led by Dr. Daniel TEH
01
Wireless Optogenetics for Vision Restoration & Neuroscience Applications:

Use of optogenetic tools to restore vision in retinal dystrophies. We are applying ultra-sensitive opsins for millisecond precision control of retinal cells in hopes of treating macular degeneration.
In neuroscience, our lab produces bi-stable ultrasensitive opsins for wireless optogenetics control of neural circuitry.

02
Photodynamic Therapy (PDT)
We utilize photodynamic therapy (PDT) for targeted induction of oxidative stress in ocular and neurological tissues. These models enable us to study disease progression and test novel therapeutic interventions. In therapeutics, we apply our wireless PDT to ablate targeted tissue such as cancers.
04
Open (waiting for you)
We are constantly open to new ideas and collaboration on phototherapeutics (optogenetics & PDT). If you are keen to collaborate, please reach out to us!
03
Wireless light delivery implantable
We are the pioneer of near-infrared wireless flexible implantable for deep tissue tether free light delivery, which has application in optogenetics and PDT.
