Swadhin Pradhan

I have just graduated from Computer Science Department of The University of Texas at Austin with a PhD. I worked with Prof. Lili Qiu. I currently work at Cisco Meraki as a Machine Learning engineer, where we are trying to bring ML capabilities across Meraki products. I was a member of the Complex Networks Research Group at IIT Kharagpur.

My research is focused on wireless sensing, mobile computing, and internet-of-things(IoT).

Recent Updates

Our paper got accepted at ACM Mobihoc 2021. This paper exploits polarization change of commercial passive RFID tags to track the rotation of a moving ball.
Our paper got accepted at ACM SenSys 2020. This paper exploits impedance change to measure temperature change using commercial passive RFID tags.
Recently gave talks at UCSD, UMichigan, MSR India, Vijna Labs, Cisco Meraki, IIT Kharagpur, IIIT Delhi, IISc Bangalore, and IIT Patna about On building interactive and secure smart spaces.
Our paper got accepted at IMWUT journal issue 3 and will be appearing in UbiComp 2019. This paper shows how we can prevent voice replay attack in voice assistants by exploting voice and wireless signature together.

Personal

Check out this independent Bengali creative platform named Swadhin Dol. It currently operates in the form of a youtube channel. The mission statement of this organization:
We are a platform for counter culture music that is in the periphery of the mainstream culture of West Bengal. Not only Bengali songs but also songs from Bengal are celebrated here. Songs in Hindi, Oriya, Bhojpuri, English, Bengali with various expressions and pronunciations are being showcased here. For the time being, the songs of Bangla Rap are predominant. The goal is to make a place for new artists. Now the means are limited, but in the future, regardless of the mainstream support, the group wants to become an alternative independent platform of Bengali music.
