Hello everyone, I need advice related to my career. I have been working in semiconductor company as an engineer for 2 years now after gradating from IIT Madras(one of the reputed technical institution in India) with a Dual Degree(BTech + MTech in 5 years) in Electrical Engg with VLSI as specialization. My interests shifted towards physics and considering to do a PhD in physics from a university abroad. So I have been trying to get in touch with basics and undergrad physics syllabus, which is basically Griffiths level and a little of classical physics. What is the level of knowledge expected before entering PhD or integrated MSc-PhD at US universities? The drawback I see with me are 1. I don't have any credentials in physics. Also, I don't have exposure to any of courses like classical, quantum, condensed matter or any graduate/undergrad courses which most of the students applying for US universities from India do. I did attend classical and quantum courses but didn't do them well at all. 2. I am an average student so undergrad grades/GPA is just average. So, I am considering to get in touch with professors at IISc(another reputed science grad school in India) and see if I can get some exposure in any research area hoping that this would fetch me recommendations which would increase my chances of getting admission at a US university. I am very much skeptical about this though. Another option I see is if I go and do MSc in Physics which would take next 3 years but I get quipped with all the necessary course work and confidence levels. I am not sure if am I going to be allowed to do this after being an MTech in Engg already. Time is also a constraint for me. Please advice.
