Introduction
I am a PhD fellow (MSCA ITN) working in Furhat Robotics, under the supervision of Prof.
Gabriel Skantze and Prof. Peter Hagoort. As part of my PhD, I plan to investigate the
areas which could contribute in enabling Social Robots to hold conversations that seem
more natural in a social setting.
More specifically, I am focusing on the role of Gaze cues/ behavior in HRI and how to model them on Social Robots.
Research Interests: Social Robotics, NLP, Emotion Modelling, Behavior Generation

Gaze cues play an important role in human communication and are used to coordinate turn-taking and joint attention, as well as to regulate intimacy. In order to have fluent conversations with people, social robots need to exhibit humanlike gaze behavior. Previous Gaze Control Systems (GCS) in HRI have automated robot gaze using data-driven or heuri...
Gaze cues serve an important role in facilitating human conversations and are generally considered to be one of the most important non-verbal cues. Gaze cues are used to manage turn-taking, coordinate joint attention, regulate intimacy, and signal cognitive effort. In particular, it is well established that gaze aversion is used in conversations to...
Data augmentation techniques have been widely used in visual recognition tasks as it is easy to generate new data by simple and straight forward image transformations. However, when it comes to text data augmentations, it is difficult to find appropriate transformation techniques which also preserve the contextual and grammatical structure of langu...
Affective behaviors enable social robots to not only establish better connections with humans but also serve as a tool for the robots to express their internal states. It has been well established that emotions are important to signal understanding in Human-Robot Interaction (HRI). This work aims to harness the power of Large Language Models (LLM)...
Speakers tend to engage in adaptive behavior, known as entrainment, when they reuse their partner's linguistic representations, including lexical, acoustic prosodic, semantic, or syntactic structures during a conversation. Studies have explored the relationship between entrainment and social factors such as likeability, task success, and rapport. S...
The increased interest in developing next-gen social robots has raised questions about the factors affecting the perception of robot emotions. This study investigates the impact of robot appearances (humanlike, mechanical) and face regions (full-face, eye-region) on human perception of robot emotions. A between-subjects user study (N = 305) was con...
With the recent advancements in the field of robotics and the increased focus on having general-purpose robots widely available to the general public, it has become increasingly necessary to pursue research into Human-robot interaction (HRI). While there have been a lot of works discussing frameworks for teaching HRI in educational institutions wit...
Developing efficient electromagnetic interference shielding materials has become significantly important in present times. This paper reports a series of (Ba1− xCax)(Ti0.9Sn0.1)O3 (BCTS) (x = 0, 0.01, 0.05, 0.1) ceramics synthesized by conventional method which were studied for electromagnetic interference shielding (EMI) applications in X-band (8–...
This paper investigates the fractional order behavior of ZnO ceramics at different frequencies. ZnO ceramic was prepared by high energy ball milling technique (HEBM) sintered at 1300 to study the frequency response properties. The frequency response properties (impedance and phase angles) were examined by analyzing through impedance analyzer (100 H...
Phonetic convergence-i.e., adapting one's speech towards that of an interlocutor-has been shown to occur in human-human conversations as well as human-machine interactions. Here, we investigate the hypothesis that human-to-robot convergence is influenced by the human's perception of the robot and by the conversation's topic. We conducted a within-s...

Emotions are the intrinsic or extrinsic representations of our experiences. The importance of emotions during a human-human interaction is immense as it formulates the basis of our interaction framework. There are several approaches in psychology to evaluate emotional states in humans based on the perceived stimuli. However, the topic has been less...
Automating robot behavior in a specific situation is an active area of research. There are several approaches available in the literature of robotics to cater for the automatic behavior of a robot. However, when it comes to humanoids or human-robot interaction in general, the area has been less explored. In this paper, a pseudo-randomization approa...
It is crucial for Social Robots to be able to respond appropriately and in an affective
manner when interacting with human beings in a social setting. The generation of affective and appropriate behavior by Social Robots during an interaction is a challenging task. This requires not only the development of robot behavior control architectures, but...
Questions
Question (1)
There have been many emotion space models, be it the circumplex model or the PANA model or the Plutchik's wheel. But all of them are used to represent human emotions in an emotion space. The definitions for arousal and valence are easy to interpret as human beings as we have some understanding of pleasant/ unpleasant or intense/non intense stimuli. However, how can we define the same for a robot? What stimuli should be considered as Arousing and what should be Pleasant for a robot? I am interested in reading the responses from researchers in the field and having a discussion in this area. Any reference to relevant literature would also be highly appreciated.
