Research Experience

• The effect of targeted melodic-speech training on Mandarin-speaking L2 learners’ perception of Cantonese level tones: Evidence from behavioral and neural tasks
  [Jun. 2025–Present]
  Leading project (Supervisor: Dr. Quentin Zhen QIN)
  • Conceptualization: Motivated the project through an in-depth literature review and identified key theoretical and methodological gaps.
  • Design: Built and deployed three training conditions in Gorilla (instructions, randomization, data export). Designed an EEG oddball paradigm and behavioral tasks in E-Prime (ABX discrimination task and a Sequence Recall Task), with triggers via StimTracker interfacing with CURRY.
  • Data collection: Recruited and tested 27 Mandarin-speaking participants; coordinated sessions and ensured protocol adherence.
  • Data analysis: Curated pilot datasets and validated response/marker alignment. Preprocessed data in Python; analyzed and visualized results in R. Conducted ERP analyses and visualized mismatch negativity components in MATLAB (EEGLAB; ERPLAB packages).
• Adult second-language learners’ consolidation of Cantonese tones during daytime naps: The role of prior knowledge
  [Jan. 2025–Present]
  Assisted project (Supervisor: Dr. Quentin Zhen QIN)
  • Project administration: Supported recruitment for a hard-to-reach population by distributing study posters on campus and assisting with online outreach (e.g., Facebook) to enroll non-tonal L1 English-speaking South Asian participants in Hong Kong.
  • Data collection: Ran sessions for 50 participants. Conducted in-lab EEG setup and recording preparation for nap sessions (cap fitting, gel injection, impedance/signal checks).
  • Data analysis: Performed sleep staging for EEG recording and curated participant-level sleep/behavior datasets. Analyzed behavioral data in R. Detected spindles/slow waves in Python (YASA) and related sleep metrics to learning outcomes using R regression models.
  • Dissemination: Prepared and submitted a first-author abstract to HISPhonCog 2026.
  • Training & supervision: Trained a part-time research assistant on standardized procedures and data-collection protocols.
• Enhancing the perception and recognition of spoken words in a second language: A cue-weighting approach
  [Oct. 2024–Present]
  Assisted project (Supervisor: Dr. Quentin Zhen QIN)

  • Data collection: Recruited and tested 60 participants; monitored completion/quality checks for a Gorilla-based online training program.
  • Data analysis: Cleaned and curated behavioral datasets; produced plots and summary statistics in R (e.g., ggplot2).
  • Dissemination: Provided feedback on poster and manuscript drafts. Co-authored a conference poster (ASA 2025) and contributed to a manuscript submitted to Cognition.

  • Design: Implemented a melodic height identification training program in JavaScript (jsPsych) with tone identification/discrimination assessments. Implemented SpeechRecorder for production assessments.
  • Data collection: Recruited and tested 30 pilot participants (15 Korean; 15 Chinese older adults) and managed end-to-end session administration.
  • Data analysis: Curated and quality-checked production/perception datasets. Automated forced alignment with Montreal Forced Aligner and extracted F0 measures; quantified tone separability/hit rates and generated tone-overlap plots; transformed accuracy to RAUs and ran statistical analyses in R.
  • Dissemination: Prepared analysis figures and draft write-ups for ongoing manuscript development.
• Perception–production links in Mandarin speakers’ English vowels: A behavioral and eye-tracking study
  [Jul. 2023–Jul. 2024]
  Undergraduate thesis (Supervisor: Dr. Hao ZHANG)
  • Conceptualization: Conducted a comprehensive literature review; led end-to-end study planning and execution, including protocol development and timeline management.
  • Design: Designed eye-tracking experiments in SR Research Experiment Builder and developed perception/production stimuli in MATLAB (TANDEM-STRAIGHT); verified task logic and output formats.
  • Data collection: Recruited and tested 60 college students in eye-tracking and production sessions; ensured consistent session documentation.
  • Data analysis: Curated and documented datasets across modalities. Automated annotation using SPPAS and DARLA; extracted F1/F2 in MATLAB (VoiceSauce). Analyzed fixation data with growth curve analysis models in R (eyetrackingR; lme4; ggplot2), and computed boundary measures in Python; produced publication-ready figures.
  • Dissemination: Wrote the manuscript and disseminated findings via a peer-reviewed journal publication and conference posters (CIEL 2024; CogSci 2024 Hong Kong Meetup).
• Music experience enhances categorical perception of English vowels in Mandarin speakers
  [Mar. 2023–Jun. 2023]

  • Data collection: Recruited and tested 24 college students; coordinated scheduling and session documentation.
  • Data analysis: Curated datasets, conducted statistical analyses in Python, and prepared a summary report with visualizations.
  • Funding: Secured university-level undergraduate research funding via a successful proposal.
  • Dissemination: Designed the project poster and presented at CIEL 2023 (poster).
