Bibliometric figures come from OpenAlex (2026-09-28) and cover the author's entire public record, not just the papers listed here. Reproducibility signal comes from Evolve's own reviews.
Research profile
Output—
Although 16 works appear in the last three years, fuller career output data for this record is insufficient to score; this axis would measure total publication volume, its trajectory, and spread across venues over time.
Impact—
Not scored: citation-based impact indicators are insufficient in this record (h-index 1, i10-index 0 on OpenAlex). The axis would measure citation counts, h-index trajectory and citation context across the full corpus.
Focus—
Insufficient topic data to score focus. The axis would measure how concentrated research activity is across fields; the 5 OpenAlex topic labels seen here (8 to 3 works each) are too coarse to rate yet.
Collaboration28/100
The collaboration score is 28/100, derived from a small network: only 3 distinct co-authors in the recent record. Recurring partners are Xiaopeng Mao, Marike Weisbjerg and Frederik Møllskov Trier, and both Evolve-reviewed 2026 papers list the author in the last position, consistent with a senior-supervision role on compact teams rather than large consortium work.
Activity83/100
Activity scores 83/100, driven by 16 works in the last three years on the OpenAlex record. The countsByYear series shows steep acceleration: 1 work in 2024, 2 in 2025 and 13 in 2026, with both Evolve-reviewed arXiv preprints appearing in 2026 — a recent, concentrated burst of output.
Reproducibility—
No score yet: reproducibility evidence (code release, data availability, benchmark protocols) is not systematically captured for this record; Evolve reviewed only 2 papers, one medium and one low. The axis would measure artifact availability across outputs.
Research summary
Sadasivan Puthusserypady is a researcher at the University of Essex (GB) working at the intersection of biomedical signal processing and machine learning, with a portfolio spanning EEG-based brain–computer interfaces, functional brain connectivity, electromyography, and cardiac electrophysiology. The OpenAlex-indexed record (identity resolved from public bibliographic data) lists 16 works over the last three years, with a pronounced acceleration in 2026 (13 works versus 2 in 2025 and 1 in 2024), yielding an activity score of 83/100. Two 2026 arXiv preprints reviewed by Evolve illustrate this direction: a strictly subject-independent EEG imagined-speech decoder in which spectral band power features outperform time-domain statistics (49.03% vs 37.97% accuracy), and a wearable ECG signal-quality assessment model using InceptionV3 on continuous-wavelet-transform scalograms that reaches 91.6% accuracy on CACHET-CADB. Both papers place the author in the senior (last) author position. Citation indicators are still thin (h-index 1, i10-index 0 on OpenAlex), and Evolve's reviews flag under-benchmarking and limited code release, so reproducibility readiness is currently low-to-medium. Collaboration is small-scale, with only 3 distinct co-authors (collaboration 28/100), centered on EEG/BCI and ECG projects.
Collaboration pattern
Collaboration is compact: the OpenAlex record shows only 3 distinct co-authors in the recent window, yielding a collaboration score of 28/100. The recurring partners — Xiaopeng Mao, Marike Weisbjerg and Frederik Møllskov Trier — appear alongside a last-author position on both Evolve-reviewed 2026 arXiv papers, suggesting supervision-style involvement with a small, stable team spanning EEG brain–computer interface and ECG signal-quality projects rather than large multi-institution consortia.

Sharp output surge in 2026
The OpenAlex countsByYear record rises from 1 work in 2024 and 2 in 2025 to 13 in 2026, with 16 works over the last three years, concentrated in EEG/BCI (8 topic works), functional brain connectivity (4) and electromyography (4).
Timeline
- 2024First year with an indexed work in the OpenAlex countsByYear record (1 work).
- 2025Output rose modestly to 2 works, ahead of the following year's acceleration.
- 2026Output accelerated to 13 works; two arXiv preprints reviewed by Evolve appeared — a strictly subject-independent EEG imagined-speech study and a wearable ECG quality-assessment study, both with the author in the last position.

About this profile
This profile is AI-structured by Evolve.Pub from public bibliographic data (OpenAlex) and Evolve's own paper reviews. It is not written or endorsed by the researcher unless the profile is claimed. Radar dimensions are computed from real bibliometrics with fixed formulas — raw figures are shown alongside; missing dimensions mean insufficient data, never zero. Errors? Claim the profile to correct or hide it.
- Bibliometric indicators (h-index, i10-index, countsByYear, topics) come from OpenAlex only; coverage for this name-resolved record may be incomplete.
- The identity is name-resolved from public bibliographic data and cannot be further verified from the inputs used for this profile.
- Only 2 papers in the Evolve catalog, both 2026 arXiv preprints; no peer-reviewed venue outcomes are covered in this profile.
- Citation impact is currently thin (h-index 1, i10-index 0 on OpenAlex), so impact-related statements should be read as early-stage.
