Brief Bio: I conduct research on security mechanisms for Internet of Things (IoT) systems and machine learning algorithms, as well as develop novel IoT systems empowered by artificial intelligence (primarily via machine learning). My objectives are to safeguard IoT systems from their vulnerabilities, make machine-learning algorithms robust to adversarial and unreliable behaviors, and develop AIoT applications that are of high economic and societal value. Prior to joining Missouri S&T, I was a Program Lead and Research Scientist at A*STAR Singapore. I earned my Ph.D. in electrical and computer engineering from the National University of Singapore.

    IEEE Internet of Things Journal (IoT-J), vol. 6, no. 3, pp. 5651-5664, June 2019.
    We propose a cross validation (CV) approach which seeks a validating crowd to ratify the contributing crowd in terms of the quality of sensor data contributed by the latter. Using a weighted random oversamping (WRoS) technique and a PATOP2 algorithm which makes an exploration-exploitation tradeoff, our proposed CV approach offers a unified solution to two typical yet disparate needs: reinforce obscure truth and discover hidden truth.

    T. Luo and S. Nagarajan
    IEEE International Conference on Communications (ICC), May 2018.
    This paper is the first work that introduces autoencoder neural networks (ANN), a deep learning model, into wireless sensor networks (WSN) to detect anomalies. It contradicts the general belief that "deep learning is not suitable for WSN" by (1) "making deep learning (extremely) shallow" and (2) allocates computation load to sensors and IoT cloud using a two-part algorithm, DADA-S and DADA-C.

    IEEE Communications Magazine, vol. 55, no. 3, pp. 68-74, March 2017.
    This survey paper provides a technical overview and analysis of six incentive mechanism design frameworks: auction, lottery, trust and reputation system, bargaining game, contract theory, and market-driven mechanism.
  • [TIST'16] Incentive mechanism design for crowdsourcing: an all-pay auction approach [ACM Lib] [pdf] [DOI: 10.1145/2837029]

    ACM Transactions on Intelligent Systems and Technology (TIST), vol. 7, no. 3, pp. 35:1-26, February 2016.
    The most commonly used auctions for incentive mechanism design are winner-pay auctions, where only winners (i.e., highest bidders who will receive reward) need to pay for their bids (by money or effort). In contrast, all-pay auctions require every bidder to pay regardless of who wins, which sounds rather unreasonable. However, applying all-pay auctions to crowdsourcing, as this paper does, gains several advantages over winner-pay auctions, and reaps much higher profit with an adaptive prize.
  • [TMC'16] Incentive mechanism design for heterogeneous crowdsourcing using all-pay contests [pdf] [DOI: 10.1109/TMC.2015.2485978]

    IEEE Transactions on Mobile Computing (TMC), vol. 15, no. 9, pp. 2234-2246, September 2016.
    Despite that crowdworkers are heterogeneous in their "types" (abilities, costs, etc.) as we all know, the hardness to model and analyze it has restricted researchers to adopt a homogeneous model where all the workers' types are assumed to follow a (single) common Bayesian belief. This paper proposes an asymmetric all-pay auction model to characterize the heterogeneity, and uses a prize tuple to achieve an interesting and counter-intuitive property called Strategy Autonomy (SA).

    What is a Tullock contest? Think it as a lucky draw! While auctions have dominated the realm of mechanism design for decades, this paper suggests Tullock contests as an alternative mechanism that is more appealing to "ordinary" participants. Tullock contests distinguish themselves from auctions in its imperfectly discriminating property: "You always have a chance to win, no matter how 'weak' you are." This feature is particularly desirable for, e.g., micro-task crowdsourcing (such as crowd sensing).
  • [TMC'15] Quality of contributed service and market equilibrium for participatory sensing [pdf] [DOI: 10.1109/TMC.2014.2330302]
    C-K. Tham and T. Luo
    IEEE Transactions on Mobile Computing (TMC), vol. 14, no. 4, pp. 829-842, April 2015.
    In order to characterize QoS for crowdsensing, this work proposes a metric called Quality of Contributed Service (QCS) which aggregates individual quality of contributions and takes into account information quality and time sensitivity. QCS is then analyzed using a market based supply-and-demand model.

Besides theory, I am also keen in developing real systems. My team has developed the following three mobile crowdsourcing/crowdsensing applications, which can be downloaded for free at Apple Store and Google Play. The latest version update was in 2018:
