I believe the answer is:

toe

I'm a little stuck... Click here to teach me more about this clue!

'little member' is the definition.
'toe' can be an answer for 'member' (toe is a kind of member). I am unsure of the 'little' bit.

'starts with thesis on electronics' is the wordplay.
'starts with' suggests taking the first letters.
The initial letters of 'thesis on electronics' is 'TOE'.

Can you help me to learn more?

(Other definitions for toe that I've seen before include "Conform-...the line" , "Digit on foot" , "End of sock" , "Small member" , "One with sock on" .)
