About
A calm way to watch clinical research
Built for volunteers, not for enrollment
We explain how studies work and what to ask — the decisions stay with you and the independent study teams.
Independent by design
Not a sponsor, not a clinic, not a recruiter.
Signal, not noise
A light pulse when categories, regions, or listings turn newly active.
Categories
All the studies we watch
Healthy Volunteer Studies
Studies that invite people without a specific condition to take part, often to help researchers understand typical responses and baselines.
Observational Studies
Researchers observe and record information over time without assigning a specific intervention to volunteers.
Behavioral Studies
Research on habits, sleep, activity, learning, and decision-making, often using apps, interviews, or guided sessions.
Prevention Studies
Studies that explore ways to help people stay well, such as lifestyle approaches, screening routines, or wellness programs.
Interventional Studies
Studies where volunteers are assigned a specific approach under a protocol so researchers can compare results.
Device Studies
Studies that look at how people use and respond to devices such as wearables, monitors, or digital tools.

FAQ
Straight answers
What does Linkage Paths actually do?We watch general clinical research opportunity categories and surface newly active listings, regions, and study types, so you can notice options early and explore at your own pace.
Are you a research organization or healthcare provider?No. Linkage Paths is an independent opportunity resource. We do not conduct research, enroll participants, determine eligibility, or provide health advice.
Do I have to sign up for text messages?Never. Every SMS preference is optional, unchecked by default, and separate. You can use the whole site without sharing a phone number, and reply STOP at any time.
What happens after I share my interests?You receive only the updates you chose. If you separately ask for a courtesy introduction, we share your details with one matching independent program — only with that extra consent.
Follow the pulse, on your terms.
